摘要： The present invention is directed to a rubber composition comprising 100 phr of at least one diene-based rubber, 30 phr to 250 phr of at least one filler, and 1 phr to 40 phr of an epoxidized and aminated fatty acid ester, wherein the epoxidized and aminated fatty acid ester is obtained from the reaction of an epoxidized fatty acid ester with an aliphatic amine. Furthermore, the present invention is directed to a rubber product, such as a tire, comprising such a rubber composition.

摘要： The present invention is directed to a rubber composition comprising 100 phr of one or more diene-based elastomers, 30 phr to 200 phr of a filler, and a benzoxazine which is the reaction of (i) a diphenol comprising two phenol groups and a bridge covalently connecting the two phenol groups, (ii) an aldehyde derivative, and (iii) an amine, wherein the bridge is connected to at least one of the phenol groups at a meta position of said at least one phenol group. The present invention is also directed to a rubber product comprising such a rubber composition and the use of such rubber products in tire components.
