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.

摘要： Disclosed is a curable composition with enhanced curing time at ambient temperatures, the curable composition including (a) a resin, e.g., 4,4′-isopropylidenediphenol-epichlorohydrin copolymer and (b) one or more curing agents, wherein a ratio of a weight percentage of the resin to a weight percentage of the curing agent or curing agents is from about 12:1 to about 15:1. Also disclosed is a method of curing a cured-in-place liner, wherein the cured-in-place liner contains the above curable composition.
