    The invention relates to a composition of polyalkylpiperidine ester derivatives and can be used in a light stabilized polymer material. Polyalkyl piperidine esters are known as light shielding agents for polymeric materials, for example 5c - (1,2,2,6,6-pentamethyl- 4-piperidyl) sebacinate Cl For practical use such known stabilizers; Not in all cases were Satisfied. because they were subject to rapid crystallization. When using solids, when necessary, also in the form of solutions, in practice, there were deficiencies that lead to difficulties, for example, to obtain light-resistant varnishes, type autolak. So well-known light protective equipment is unsuitable for use in lacquer systems with low solvent content. The aim of the invention was to reduce crystallisability during storage. The goal is achieved by the fact that the composition of stabilizers based on b is ll, 2, 2, 6, b-pentamethyl -4-piperidinyl) sebacinate (component J), additionally contains 6-gb5 mas mono- (1,2,2,6, 6-pentamethyl-4-piperidine) methyl sebacate (component C) Stabilizers are introduced into polymers materials at a concentration of 0.01-5 May in the calculation is not subject to stabilization of the material. Advantageously, 0.03-1.5 wt.%, Particularly preferably 0.2-0.6 wt.% Of the compounds are added, based on the material to be stabilized. Introduction can be carried out by polymerization, for example, by introducing by mixing the compounds and other additives into melt by methods commonly adopted in the art, prior to or during molding, as well as by applying dissolved or dispersed compounds to the polymer during subsequent evaporation of the solvent. New blends can also be added to polymeric materials to be stabilized in the form of a concentrate that contains these compounds, for example, in an amount of 2.5-25 wt.% O In the case of cross-linked polyethylene, compounds are added to them before crosslinking. In addition to mixtures of components I and | Other well-known stabilizers or stabilizers can be added to polymeric materials. For example, antioxidants, UV absorbers, deactivators can be such. metals. The polymeric materials thus stabilized may be taken in various forms, for example in the form of films, fibers, strips, profiles, plates or articles obtained by injection molding. They are also used in the foamed state. In addition, they can also be used as binders for paints, adhesives or putties, and also as laminates and substrates in photographic materials. Example 1. 230.3 g (1 mol) of dimethyl ester of sebacic acid and 308.3 g of D1, R mol) 1,2,2,6,6 pentamethyl-4-hydroxypiperidine nag-, rotate to about together with. 120 ml of xylene in a weak stream of nitrogen. 1 g of tetrabutyl orthotitanate was added to the reaction mixture and further heated in a weak stream of nitrogen to 130140 ° C. Very soon, the distillation of methanol-7-xylene is uniform. The temperature in the reaction mixture rises up to 160 ° C for 3-4 hours and the contents of the flask are further stirred at this temperature until after about 10 hours practically nothing will be distilled off. The last traces of solvent are removed by distillation under high vacuum at about, 001 mm pToST. and the residue in the flask is clarified through a sintered glass filter. The yellow light yellow oil suspension liquid is a mixture of about 85% S (- 1,2,2,6,6-pentamethyl-4-piperidinyl) - dogation acid monomethyl ester and about 15% mono- (1,2,2,6 , 6-pentamethyl-4-piperidinyl dog acid monomethyl ester Example 2. Tendency to crystallization of the proposed mixtures of esters. however, if you wish flax is a stable liquid ether mixture, the proportion of component i can be easily increased. Component I is 5s .- (1,2,2,6,6-pentamethyl-4-piperidinyl) sebacinate and component J is mono- ( 1,2,2,6,6-pentamethyl4-piperidinyl) -methylsebaccinate The ester mixtures are stored at (-20: fc and the time until complete crystallization is determined. Increasing the time means increasing the stability of the liquid consistency of the ester mixture (table). Assuming a stabilized composition that is long in liquid form and can be used in various polymer systems, 25 at the same time, it is necessary to add an extremely large and undesirable amount of solvent to obtain similar unsatisfactory results when using a known composition.
