<p>Block-copolymers of the A-B-C pattern wherein A is an alphamethylstyrene, vinylbiphenyl, isopropenylbiphenyl, vinylnaphthalene or isopropenylnaphthalene block, B is a diene block or a hydrogenated diene block and C is a pivalolactone block are prepared by sequentially polymerising first A and then B to form a lining AB block copolymer, reacting this with CO2 to form a carboxyl function, and reacting pivalolactone with the carboxyl-functional AB copolymer.</p> |
