Abstract:
A method of forming a block copolymer, said method comprising:reacting a substrate compound with a chain transfer agent in the presence of an alkali metal catalyst to form a telechelic oligomer, wherein the substrate compound is selected from the group consisting of polycarbonates, polyesters, polyurethanes, polyarylates, cyclic esters, cyclic carbonates, and cyclic urethanes; and reacting said telechelic oligomer with at least one additional compound selected from the group consisting of monomers of styrene, styrene derivatives, acrylate, methyl acrylate, methyl methacrylate, fluorinated acrylate, acrylonitrile, ethylene, butadiene, vinyl acetate, and vinyl chloride in a radical polymerization process, to produce a block copolymer.
