NOVEL POLYMERS AND THEIR APPLICATION IN OBTAINING HIGH-IMPACT POLYMER COMPOSITIONS Russian patent published in 2014 - IPC C08F216/12 C08F230/08 C08F212/10 C08L29/00 C08L25/12 

FIELD: chemistry.

SUBSTANCE: invention relates to a polymer functionalised on terminal groups. The polymer contains a product of reaction between a living polymer and, at least, one component, selected from the group, consisting of: (a) allylglycidyl ether, described by formula (I) CH₂=CHCH₂OCH₂-X, where X represents the following epoxy group:

,

where R¹, R² and R³ are identical or different and are selected from hydrogen, alkyl or aryl groups, containing from 1 to 30 carbon atoms; (b) allylhalogensilane, described by formula (II) CH₂=CHCH₂Si(R¹R²)-X, where R¹ and R² are identical or different and are selected from alkyl or aryl groups, containing from 1 to 30 carbon atoms, and X represents halogenide, selected from chloride, bromide and iodide, and (c) combination of (a) and (b). The living polymer represents a living polymer of a diene monomer or a living polymer of a diene monomer and a vinylaromatic hydrocarbon monomer.

EFFECT: claimed are: the functionalised on terminal groups polymer (versions), a method of obtaining the functionalised on terminal groups polymer and a rubber-modified high-impact polymer composition; functionalised on terminal groups polymers are used to obtain high-impact polymer compositions.
