FIELD: chemistry. ^ SUBSTANCE: rubber mixture contains rubber, filler selected from a group comprising silicic acids, silicates, additional ingredients used if necessary and at least one organosilane of general formula I R1R2R3SiR4 - SH (I), in which R is methyl or ethyl, R is a methoxy group, ethoxy group or -O-(Y-O)m-X group, where Y is a branched or straight, saturated or unsaturated hydrocarbon group with a double bond, X denotes a C1-C9alkyl group and m is a number from 1 to 40, R3 is methyl, ethyl or is identical to R2 and R4 is a branched or straight, saturated or unsaturated aliphatic C1-C12 hydrocarbon group with a double bond. Rubber mixtures are obtained by mixing rubber, filler, additional ingredients used if necessary and at least one organosilane of general formula I. Rubber mixtures can be used to mould articles. ^ EFFECT: invention increases wear resistance and resistance to growth of cracks. ^ 7 cl, 11 tbl, 11 ex |
