ABSTRACT:
Poly(vinyl chloride) exhibits a useful combination of acceptable flow for injection molding, improved processability, and acceptable heat distortion resistance and toughness when modified with a multi-stage polymer having as one stage an alkyl (meth)acrylate polymer or copolymer containing a low level of a copolymerized unsaturated acid partly to completely in the form of its alkali metal salt. In preferred compositions, the melt viscosity under injection molding conditions of the blend will be equal to or less than that of the PVC alone.
