More Information
Summary:A thermoplastic blend useful for the preparation of molded articles comprising a rigid thermoplastic polymer and a tapered triblock elastomer of a monovinylidene aromatic monomer and butadiene having a ratio of monovinylidene aromatic monomer:butadiene of 10:90 to 60:40; average molecular weight from 50,000 to 135,000. The blend is easily prepared by extrusion blending or other techniques and does not require an extender oil in its preparation.
