Abstract
Official abstract text for this publication.
The present invention is directed to a method of making a copolymer, comprising the steps of at least partially epoxidizing a polyisoprene to produce an epoxidized polyisoprene; reacting the epoxidized polyisoprene with a dithiol to produce a thiol functionalized polyisoprene; and reacting the thiol functionalized polyisoprene with a thiolophile-functionalized polymer derived from a monomer having a hydrogen bond donor site and hydrogen bond acceptor site to form the copolymer.
