METHYLSTYRENE CONTAINING HYDROXYL GROUPS AND POLYMERS BASED THEREON Russian patent published in 2019 - IPC C08L25/04 C08L21/00 C08F12/08 

FIELD: chemistry.

SUBSTANCE: invention relates to elastomer compositions containing one or more reinforcing fillers. Described is a method of producing a polymer compound containing a monomer link of polyene, involving a) anionic initiation of polymerisation of at least one type of polyene and a compound having general formula

,

where m denotes integer from 2 to 5, and each group G_p independently, is a protective group, wherein said at least one type of polyene is polymerised before polymerisation of said compound, and where number of links obtained from said compound is from 1 to 10, thereby obtaining a polymer, and b) one of polymer quenching, polymer reaction with compound terminating chain growth, or polymerisation of additional amounts of said at least one type of polyene.

EFFECT: technical result is improved adhesion and rolling resistance.
