TRIALKYLSILYLOXY-TERMINATED POLYMERS Russian patent published in 2016 - IPC C08L33/04 C08F8/00 C08L9/00 C08L9/06 B60C1/00 

FIELD: chemistry.

SUBSTANCE: present invention relates to polymers containing functional end groups, and their production. Method involves anionic polymerisation in solution, wherein one or more bis-(trialkylsilyl) peroxides (functional reagents) of general formula (II) where R¹, R², R³ may be same or different, and denote alkyl, cycloalkyl, or aralkyl, which may contain heteroatoms, such as O, N, S, Si, in form of pure substance, solution, or suspension, are added to polymers with reactive ends of polymer chains, selected from group of polybutadiene, polyisoprene, copolymer of butadiene and isoprene, copolymer of butadiene and styrene, copolymer of isoprene and styrene, or triple copolymer of butadiene, isoprene, and styrene.

EFFECT: technical result is development of polymers with functional terminal groups of suitable steric screening for producing hydroxy-terminal polymers.
