Abstract

Triblock copolymers containing a copolymer having a number-average molecular weight of from 3,000 to 300,000, a molecular weight polydispersity of from 1.05 to 2.0, and an A-B-C structure in which each of the blocks A and C may be a monomer sequence chosen from an acrylic, a vinylaromatic, a methacrylic or a maleimide monomer, and block B may be a monomer sequence chosen from an acrylic, a vinylaromatic or a methacrylic monomer, where at least one of the blocks A and C is different than block B.
