Abstract:
1. A composition comprising: 30 to 93 weight percent of a polar polymer selected from the group consisting of cellulose esters, poly(alkyl (meth)acrylate)s, polyamides, polycarbonates, polyesters, polyetherimides, polysulfones, polyethersulfones, poly(ethylene-ethyl acrylate)s, poly(ethylene-vinyl acetate)s, polyurethanes, poly(vinyl acetate)s, poly(vinyl alcohol)s, poly(styrene-acrylonitrile)s, poly(styrene-maleic anhydride)s, poly(vinyl butyral)s, and combinations thereof; 5 to 68 weight percent of a non-polar polymer selected from the group consisting of unhydrogenated block copolymers of alkenyl aromatic compounds and conjugated dienes, hydrogenated block copolymers of alkenyl aromatic compounds and conjugated dienes, poly(alkenyl aromatic)s, poly(phenylene ether)s, and combinations thereof; and 2 to 20 weight percent of a poly(phenylene ether)-poly(hydroxy ether) block copolymer comprising at least one poly(hydroxy ether) block, and at least one poly(phenylene ether) block; wherein the mole ratio of poly(hydroxy ether) blocks to poly(phenylene ether) blocks is 0.95:1 to 1.00:1; wherein all weight percents are based on the total weight of the composition, unless a different weight basis is specified.
