Title: HIGH RIGIDITY RUBBER COMPOSITION
Abstract:
Rubber compositions having a particular rigidity booster and articles made therefrom. Such rubber compositions include a highly unsaturated diene rubber having a content of units of diene origin that is greater than 50 mol% and a reinforcing filler. Also included in such rubber compositions are a methylene acceptor and a methylene donor that form a methylene donor/methylene acceptor reinforcing resin system. The rubber compositions additionally include the rigidity booster that has a structure as formula (I), where R is a saturated or unsaturated aliphatic moiety having a chain length of between C10 and C30, and M+n is a metallic cation selected from K+, Na+, Zn++, Ca++, Mg++ or combinations thereof, and wherein the rubber composition includes no cobalt compounds.
