Abstract:
1. A composition, comprising a graft copolymer having segmented arm(s), wherein the graft copolymer has a polymeric backbone and at least two polymeric segments that form the arms, said segments being grafted onto the backbone, wherein (a) the backbone is of polymerized ethylenically unsaturated monomers; and (b) the segmented arm(s) are of polymerized ethylenically unsaturated monomers that are attached to the backbone via a single point on the segmented arms, and wherein the at least two polymeric segments comprise differing compositions from those of adjacent segment(s), and (c) wherein the segmented arms are either: (i) block type segments formed from combinations of two monomers (AB) or three monomers (ABC) or (ii) tapered structure.
