Abstract
Official abstract text for this publication.
The present invention is directed to a copolymer comprising: a polymeric backbone chain derived from a monomer comprising at least one conjugated diolefin monomer and optionally at least one vinyl aromatic monomer; and a polymeric side-chain bonded exclusively to a terminal end of the backbone chain, the side-chain comprising a polymer derived from a monomer having a hydrogen bond donor moiety and a hydrogen bond acceptor moiety.
First claim
Opening claim text (preview).
What is claimed is: 1. A copolymer comprising the structure X—R—O—R′—S—Z (I) where X is a polymer derived from a monomer comprising at least one conjugated diene monomer and optionally at least one vinyl aromatic monomer; S is sulfur; Z is a polymer derived from a monomer having a hydrogen bond donor site and a hydrogen bond acceptor site; R is a covalent bond or an alkyl group of 1 to 12 carbon atoms bonded to a terminal end of X; O is oxygen; and R′ is a divalent…
