Abstract RU 2099356 C1

FIELD: modifying of rubber on the base of polyisoprene caoutchouc. SUBSTANCE: oil polymer resin which is prepared by radical copolymerization of piperylene fraction, styrene and liquid fraction of pyrolysis of hydrocarbons having composition C5-C10 (a), or C8-C10 (b) or C9-C10(c) is proposed as modifying agent. Mass ratio of reagents for variant (a) is 1:0.8-2.5: 5-15, mass ratio for variant (b) is 1:3.5:3-5, mass ratio for variant (c) is 1:0.7-3.5:3-4, is proposed as modifying agent. Said radical copolymerization is initiated by hydroperoxide of alkyl benzene. Adhesion of resin to metal is increased by 1.22-1.37 times. EFFECT: increased adhesion of resin to metal. 5 tbl
