Abstract:
Described herein is a composition comprising a polymeric blend of: (i) a first polymer comprising at least one acrylic block copolymer, wherein the at least one acrylic block copolymer comprises: (a) at least two A block polymeric units wherein each A block has a glass transition temperature of at least 90 C and each A block is independently derived from a monoethylenically unsaturated monomer comprising a first (meth)acrylate monomer; and (b) at least one B block polymeric unit wherein the at least one B block has a glass transition temperature no greater than −30 C and wherein the at least one B block is derived from a monoethylenically unsaturated monomer comprising a second (meth)acrylate monomer; and (ii) a second polymer selected from at least one of a polyvinyl acetal resin, a polyvinyl acetate, and a cellulose ester.
