The product has improved green strength, and may be blended with other rubbers and with conventional compounding ingredients. In examples, the amines used are N,N,N<SP>1</SP>,N<SP>11</SP>,N<SP>111</SP>,N<SP>111</SP>-hexamethyltriethylene tetramine, triethylene diamine, N,N-dimethyl benzylamine, N-methylpiperidine, N,N,N<SP>1</SP>,N<SP>1</SP> - tetramethylhexamethylene diamine, N,N-dimethyldodecylamine, N,N - dimethyloctadecylamine and N,N-dimethylhexylamine.

    The invention relates to the rubber industry, in particular, to the development of a method for the modification of bromobutyl rubber.
    A known method of modifying bromobutyl rubber by mixing with an organic amine, for example, phenylamine; with subsequent aging at 160 ° C. fi.
    Rubber obtained on the basis of known rubber, have insufficient strength properties.
    The purpose of the invention is to improve the strength properties of rubbers based on modified bromobutyl rubber.
    The goal is achieved by the method of modifying a bromobutyl rubber by mixing with an organic amine followed by an extract using an organic amine selected from the group: methyl (ethyl) piperidine, methyl (ethyl) piperazine, triethylenediamine, action

    And exposure is carried out at 25-150 ° C for 1-48 hours.
    Example 1. The bromobutyl rubber used has a Myi. Number of 45 and contains
    IS 2.0 wt.% Bromine.
     Bromobutyl rubber (IBD) samples are reacted with various amounts of a number of amines. Reaction
    2 & between the rubber and the amine is carried out at the intermixing of the rubber in the mill at about the addition of the necessary amount of amine. The polymer is then rolled into a sheet.
    25 and heated in an air circulating dryer for 16 hours in order to ensure that the reaction of the amine with the polymer is complete. A composition is prepared from the obtained polymer according to the following formulation, parts by weight.

    The strength of this composition is then determined in its unvulcanised state.
    Table 1 shows the names of the amines used, their amount and the results of measuring the strength of the composition in the unvulcanized state at room temperature. The results clearly show the increased strength of the unvulcanized polymer composition.
    In addition, samples of these compositions are ground at approximately and extruded at. and a screw rotation speed of 70 rpm. It was found that, basically, the characteristics of the composition during grinding and extrusion do not differ significantly from similar characteristics of the composition before grinding.
    Example 2. The bromobutyl polymer samples described in Example 1 are then treated with various amounts of monoamines, such as: N, N-dimethyldodecylamine, N, N-dimethyloctadecylamine and M, M-dimethylhexylgly The treatment is carried out in a mill, as in Example 1 and then perform the same heat treatment. From the obtained treated samples of bromobutyl polymer, the compositions are prepared according to the formulation described in Example IFa and then they are tested.
    The results are presented in table 2.
    Grinding and extrusion is carried out on samples treated with M, N-dimethyldodecylamine in the amount of 0.45 weight.h, per 100 weight.h. bromobutyl rubber.
    The solvent in cyclohexane of the starting bromobutyl is 96.4%; the solubility of the polymer, processed; N, M-dimethyloctadecyl-AU is 91.3%, i.e. no significant change in solubility.
    Example 3 A portion of the samples (described in example 1, processed and mixed into a composition as described) are tested to determine the time for premature vulcanization. and then answer. The resulting curing agents are stretched.
    The results are presented in table 3. From these results, it can be seen that no significant effect on the properties of the vulcanizates is found.
    Example 4. Samples of bromobutyl rubber from example 1 are treated with N, N-dimethyloctadecylamine (0.4 weight.h.
    at 1.00 weight.h. bromobutyl rubber)
    As described in Example 1, it is heat-treated and blended into a composition for making tire liners. The strength of the composition in an unvulcanized state is determined.
    and also tests are performed to determine the time of premature vulcanization, then the compositions are cured and the vulcanizates are tested to determine tensile properties.
    When compared with a control sample based on the known bromobutyl, it was found that the properties of the vulcanizates of the compositions according to the invention did not change significantly. Improved
    the strength of the compositions in the unvulcanized state appears when they are mixed with the second rubber.
    ; Table 4 presents the formulations of the preparation of the compositions and the results of tests of vulcanizates.
    Example 5. Samples of bromobutyl rubber from example 1 is treated
    dodecylamine or octadecylamine, as described in example 1, and heat-treated for 16 hours at / 90 ° in an oven. Processed samples of bromobutyl rubber are tested for strength
    compositions in an unvulcanized state as previously described.
    The results are presented in table.5. As follows from the table.1-5, the proposed method of modifying BBK has
    mainly before the well-known for its durable properties and the possibility of recycling at elevated temperatures of 1X.
