主权项

1. A process for preparing an amino-functionalized block copolymer comprising:
in an inert hydrocarbon solvent and in the presence of an initiator, (a) polymerizing a hard end block A, the block A having a melting temperature of at least about 20° C.; (b) polymerizing a soft interior block B, the B block having a Tg of at most 20° C.; (c) polymerizing a block D from a plurality of p-vinylbenzylamino derivative monomers, the p-vinylbenzylamino derivative monomers capable of being polymerized at a temperature range of from 20° C. to 60° C.; thereby forming a block polymer or a living block polymer comprising the blocks A, B and D.
