Известен способ получени органокремпийорганических полимеров сополимеризацией винилтрпорганосилапа, содержащего алкильпый радикал с числом углеродных атомов более 5, и сопр женного диена (изопрена или бутадиена). Сополимеризацию провод т в присутствии литийорганического катализатора при 10-80°С. Содержание диенов в полученных сополимерах 5-15 вес. %. Получают эластомерпые полимеры.A known method for producing organocampy organic polymers is a copolymerization of vinyl terpangasilap containing an alkyl group with a carbon number of more than 5 and a conjugated diene (isoprene or butadiene). The copolymerization is carried out in the presence of an organolithium catalyst at 10-80 ° C. The content of dienes in the obtained copolymers of 5-15 weight. % Elastomer polymers are obtained.

Процесс сополимеризации провод т в присутствии литнйорганических инициаторов. В качестве органического компонента в алкилахThe copolymerization process is carried out in the presence of organotol initiators. As an organic component in alkyls
лити предпочтительно использование разветвленных углеводородных радикалов, например изопропиллити , вторичного бутиллити , изоамиллити и других, из-за их большой скорости взаимодействи с мономерами, участвующими в процессе сополимеризации. Сополимеризацию осуществл ют в массе или в углеводородных растворител х: низших алканах нормального и изостроени с числом углеродных атомов 5-10, ароматических, циклоалифатических, а также их смес х, например циклогексане, бензоле, толуоле, гексане , их смес х и др. Сополимеризацию провод т при 10-80°С, предпочтительно при 40- 60°С.Lithium is preferably the use of branched hydrocarbon radicals, such as isopropyl lithium, secondary butyl lithium, isoamily, and others, because of their high rate of interaction with the monomers involved in the copolymerization process. The copolymerization is carried out in bulk or in hydrocarbon solvents: lower normal alkanes and isostructures with 5-10 carbon atoms, aromatic, cycloaliphatic, and their mixtures, for example cyclohexane, benzene, toluene, hexane, their mixtures, etc. Copolymerization is carried out at 10-80 ° C, preferably at 40-60 ° C.
Концентрацию инициатора можно измен ть в широком интервале в зависимости от требуемого молекул рного веса по соотношениюThe initiator concentration can be varied over a wide range depending on the desired molecular weight by the ratio

где MI и М2 - концентраци (в мол х) мономеров; / - концентрацн (в мол х) инициатора .where MI and M2 are the concentration (in mol x) of the monomers; / - concentration (in mol x) of the initiator.
Соотношение мономеров в исходной смеси может измен тьс в широком интервале в зависимости от требований, предъ вл емых к конечному продукту: например, количествеThe ratio of monomers in the initial mixture may vary over a wide range depending on the requirements for the final product: for example, the quantity
