Abstract
The present invention concerns block and/or tapered block copolymers comprising pendant hydrocarbyl, trisubstituted epoxide-containing moieties, and methods of preparing these and their precursors. The invention also concerns curable compositions comprising such copolymers as modified solution styrene butadiene rubbers and silica and/or carbon black and articles formed from curing these formulations. Such articles may be tyres.
Claims35
A method comprising effecting an epoxidation reaction on a first copolymer, to provide a second copolymer comprising epoxide groups, wherein the first copolymer is a block and/or tapered block copolymer which is derived from at least three different types of monomer and comprises a backbone from which hydrocarbyl, trisubstituted ethylene-containing moieties are pendant.
