GRAFT COPOLYMERS WITH GRAFTED POLYMERIC ARMS THEIR PREPARATION AND USE

摘要

A graft copolymer composition including: a polymeric backbone derived from a plurality polymerizable ethylenically unsaturated monomers; and a plurality of polymeric arms attached pendant to the polymeric backbone. The polymeric arms include: (a) at least two different polymeric arms comprising: a condensation copolymer arm and a random copolymer arm (b) a polymeric arm having segments of (i) a condensation copolymer segment and (ii) a random copolymer segment wherein said condensation copolymer segment and random copolymer segment are linked to each other; (c) or combinations thereof.
