Abstract

Disclosed are compositions comprising (i) a rigid thermoplastic resin comprising structural units derived from a (C.sub.1-C.sub.12)alkyl (meth)acrylate monomer, and optionally a second monomer selected from the group consisting of a vinyl aromatic monomer, a monoethylenically unsaturated nitrile monomer and mixtures thereof, and (ii) a fluoropolymer additive comprising 30 wt. % to 70 wt. % of a fluoropolymer and 70 wt. % to 30 wt. % of a carrier polymer comprising structural units derived from a vinyl aromatic monomer, or a monoethylenically unsaturated nitrile monomer, or mixtures thereof, wherein the fluoropolymer is at least partially encapsulated by the carrier polymer and wherein the amount of fluoropolymer present in the composition is in a range of 2 parts by weight (pbw) to 25 pbw based on 100 pbw of the composition, and wherein the composition is free of both rubber component and filler. Articles made from the compositions and a method to improve physical properties in the compositions are also disclosed.
