    摘要： A particulate interpenetrating network polymer that is composed of a polyolefin polymer and a vinyl aromatic polymer that includes residues of (meth)acrylic acid, is described. The particulate interpenetrating network polymer is formed by polymerization of a vinyl aromatic monomer composition substantially within the polyolefin polymer. The vinyl aromatic monomer composition includes vinyl aromatic monomer (e.g., styrene) and a comonomer that is composed at least in part of (meth)acrylic acid (e.g., (meth)acrylic acid and optionally butyl(meth)acrylate). The amount of (meth)acrylic acid present within the comonomer (and accordingly the vinyl aromatic polymer) is selected such that a molded article prepared from expanded particulate interpenetrating network polymer, has a volume shrinkage value of less than or equal to 5 percent, when subjected to a temperature of 100° C. for 24 hours. Also described is an expandable particulate interpenetrating network polymer that includes the particulate interpenetrating network polymer of the present invention and an expansion agent (e.g., pentane) impregnated therein.

    摘要： A method of reducing the odor of a resin that includes the step of adding about 0.1% to about 10% by weight of an absorbent clay to the resin. A resin composition with low odor is provided that includes 60% to 99.9% of a styrenic polymer; optionally 0.1% to 30% of one or more elastomeric polymers; and 0.1% to 10% of an absorbent clay. The styrenic polymer is formed by polymerizing a mixture containing 35% to 100% by weight of one or more styrenic monomers, optionally 1% to 49% by weight of one or more maleate-type monomers, and optionally 1% to 65% by weight of one or more other polymerizable monomers. The resin composition and/or method can be used to make molded articles or a resin foam.
