“POLYMER CONTAINING SULFUR WITH TERMINAL MODIFICATION, COMPOSITION AND OPENING SEALED WITH A SEALER” Field [0001] This disclosure relates to difunctional polymers containing sulfur with terminal modification, compositions comprising difunctional polymers containing sulfur with terminal modification, and methods for using polymers terminal sulfur-containing difunctional compounds.
Background [0002] Sulfur-containing polymers terminated by thiol are well known for being well suited for use in various applications such as aerospace seal compositions due, in large part, to their resistance to fuels. Other desirable properties in aerospace sealant compositions include flexibility at low temperatures, short cure times (the time required to achieve a predetermined resistance), and resistance at high temperatures, among others. Sealing compositions exhibiting at least some of these characteristics and thiol-terminated sulfur-containing polymers are described, for example, in US Patent Nos. 2,466,963, 4,366,307, 4,609,762, 5,225,472, 5,912,319, 5,959,071 , 6,172,179, 6,232,401, 6,372,849, and 6,509,418. Polyethers that are liquid at room temperature and pressure and that have excellent flexibility at low temperatures and resistance to fuels, such as those disclosed in U.S. Patent No. 6,172,179, are also useful in aerospace seal applications. For example, difunctional polyethers having hydroxyl end groups prepared by reacting a hydroxyl-containing compound with an aldehyde are described in GB 850,178 and in U.S. Patent Nos. 3,290,382, 3,959,227, and 3,997,614.

Summary [0004] Sulfur-containing polymers, finished with other functional groups, can allow the use of alternative curing chemicals and can provide sealants having improved properties appropriate for aerospace sealant applications.

Example 13 Thiol-terminated sulfur-containing polymer [0185] Dimercapto-dioxa-octane (4.06 g), the acrylate-terminated sulfur-containing polymer of Example 3 (93.6 g), and VAZO®-67 (1 , 1 g, obtainable from DuPont) in a 500 mL round bottom flask with 4 necks. The flask was equipped with a thermal blanket, thermocouple, temperature controller, an inlet for positive nitrogen pressure, and a mechanical stirrer (PTFE support and mixer). The mixture was stirred at ca. 200 rpm and heated to 80 ° C and maintained at 80 ° C for 15 h. During the reaction, VAZO®-67 (1.0 g) was loaded into the reaction mixture. The resulting polymer had an equivalent mercaptan weight of 4,834 and a viscosity of 299 Poise.
Example 14 Performance data of the thiol-terminated sulfur-containing polymer of Example 12 [0186] The curing reaction was carried out in a 100 g plastic container equipped with a lid. The thiol-terminated sulfur-containing polymer described in Example 13 (51.3 g), diethylene glycol divinyl ether (7.91 g) and IRGACURE® 2022 (0.30 g, 0.5% by weight) were manually mixed in the container ). Then, the container was placed in a speed mixer (DAC 600 FVZ) and mixed for 1 min at 2,300 rpm. The polymer was poured into a circular metal lid (5 inches in diameter) (pretreated with Valspar 225 release agent), and placed under ultraviolet radiation for 15 seconds, after which the polymer was completely cured. A Super Six curing unit (Fusion Systems Inc.) was used to provide UV radiation. The curing unit was equipped with a 300 W H bulb, which produced UV wavelengths ranging from 200 nm to 450 nm. A total UV energy dosage of 3.103 J / cm2 was measured using a UV feed unit (EIT, INC., Sterling, VA) was applied to the polymeric composition.
Example 15 Reaction of sulfur-containing polymer with methyl acetate mercapto [0187] The sulfur-containing polymer of Example 2 (89.6 g), methyl mercapto-acetate (21.4 g) and sodium methoxide (0, 4 g) in a 300 mL round bottom flask with 3 necks. The flask was equipped with a thermal blanket, thermocouple, temperature controller, mechanical stirrer (support and PTFE mixer), and a Dean-Stark siphon connected to a reflux condenser and topped with an inlet for positive nitrogen pressure. The mixture was heated to 150 ° C and stirred at 300 rpm. The temperature of the mixture was maintained at 150 ° C for 48 h. The solvent was removed in vacuo for 1.4 h. The resulting polymer had a viscosity of 41 Poise and an equivalent mercaptan weight of 6,934.
Example 16 Reaction of sulfur-containing polymer with mercapto-acetic acid [0188] The sulfur-containing polymer of Example 2 (89.6 g), mercapto-acetic acid (13.8 g), hafnium chloride / THF complex was loaded (HfCl4.2THF, 1.20 g, obtainable from Aldrich) and toluene (75 ml) in a 300 ml round bottom flask with 3 necks. The flask was equipped with a thermal blanket, thermocouple, temperature controller, mechanical stirrer (support and PTFE mixer), and a Dean-Stark siphon connected to a reflux condenser and topped with an inlet for positive nitrogen pressure. The mixture was heated to 130 ° C and stirred at 300 rpm. The temperature of the mixture was maintained at 130 ° C for 18 h. NaHCO3 (12.8 g) was added to the reaction mixture to consume excess mercapto-acetic acid during brief stirring for 4 min. The product was filtered through a Büchner funnel with Whatman GF / A paper (diameter 7.0 cm) and completely washed with 100 ml of toluene. The resulting filtrate was extracted under vacuum (rotary evaporator, water bath at 90 ° C, final vacuum less than 5 Torr) to produce 90.1 g of a viscous polymer having a viscosity of 52 Poise and an equivalent weight of mercaptan of 4,223.
Example 17 Reaction of polyform polymer with TDI and mercapto-propanol [0189] The sulfur-containing polymer from Example 2 (89.6 g) and toluene diisocyanate (17.5 g) was loaded into a 300 ml round-bottom flask with 3 bottlenecks. The flask was equipped with a thermal blanket, thermocouple, temperature controller, mechanical stirrer (support and PTFE mixer), and a nitrogen inlet. The mixture was heated to 71 ° C and stirred at 200 rpm and maintained at 71 ° C for 27 h. Then, 3-mercapto-propanol (7.9 g) was added and the reaction mixture was heated to 77 ° C and stirred at 200 rpm for 41 h. Finally, the mixture was heated to 100 ° C under vacuum for 30 min to remove unreacted 3-mercapto-propanol. The resulting polymer had an equivalent mercaptan weight of 2,630. Example 18 Epoxy-terminated sulfur-containing polymer [0190] A 60% dispersion of sodium hydride in mineral oil (Aldrich) (1.92 g) was loaded into a 4-necked round-bottom flask equipped with a thermal blanket, pair thermoelectric, temperature controller, an input for positive nitrogen pressure, and a mechanical stirrer, and covered with nitrogen. The dispersion was washed three times with 5 ml of heptanes. The reaction was stirred at room temperature, followed by the addition of a premixed polymer solution containing sulfur from Example 2 (157.08 g) and dry dimethyl sulfoxide (312 g) for 45 minutes. The reaction was stirred at ca. 200 rpm for 4 hours and epichlorohydrin (11.10 g) (Aldrich) was added dropwise while the reaction released heat at 50 ° C. The reaction was maintained at 50 ° C for 2 hours, cooled to room temperature, and stirred overnight. Then, the solution was poured into 1,100 g of water and extracted twice with methylene chloride, washed with a saturated aqueous solution of NaCl, and dried over sodium sulfate. The solvent was removed in vacuo to provide a light brown oil with an epoxy equivalent weight of 1,960 g / meq. [0191] Finally, it should be noted that there are alternative ways to implement the incorporations disclosed here. Consequently, the mergers present are considered illustrative and not restrictive. In addition, the claims are not limited to the details given here, and enable its full scope and equivalents thereof.
