Abstract
A method of making a graft copolymer, comprising the steps of obtaining a first polymer comprising at least one carbon-carbon double bond, the first polymer derived from at least one first monomer, the at least one first monomer comprising a conjugated diene monomer; obtaining a second polymer, the second polymer capable of exhibiting a lower critical solution temperature (LCST) and comprising a terminal functional group capable of reacting with the carbon-carbon double bond; and reacting the second polymer with the first polymer to form a graft copolymer, the graft copolymer comprising a backbone derived from the first polymer and sidechains derived from the second polymer.
