Abstract

A filled polymer composition which comprises PA0 A) from about 5 to about 90 percent of one or more thermoplastic substantially random interpolymers prepared by polymerizing one or more a-olefin monomers with one or more vinylidene aromatic monomers and/or one or more hindered aliphatic or cycloaliphatic vinylidene monomers, and optionally with other polymerizable ethylenically unsaturated monomer(s), and PA0 (B) from about 10 to about 95 percent of one or more inorganic fillers, PA0 the amounts of (A) and (B) being based on the total weight of (A) and (B). Fabricated articles made from the filled polymer compositions are useful as sound insulating or energy absorbing films or sheets or as floor, wall or ceiling coverings.
