Synthetic rubber mix

摘要

The present invention relates to a rubber mix based on synthetic rubbers and containing vulcanizing agents, organic accelerators, vulcanization promotors, fillers, dispersing agents, plasticizers and an alkylphenolamine resin prepared by condensation of aminomethylating agents with a mixture consisting of 70-97% by weight of monoalkylphenols with the aklyls being C4-C12 and 3 to 30% by weight of dialkylphenols with the alkyls being C4-C12 at a temperature within the range of from 120 DEG to 180 DEG C; said alkylphenolamine resin corresponds to the formula: <IMAGE> +tr <IMAGE> wherein R is a C4-C12 alkyl; R' is hydrogen or substituted hydroxybenzyl; R'' is hydrogen, a C4-C12 alkyl, N(dimethyl) methylenamine; n = 0.1-5.0; m = 0 - 4; z = 0 - 0.
