    摘要: Refrigerator and freezer liners are molded from rubber modified graft copolymers of acrylonitrile and methyl acrylate. These polymers comprise 14 to 30 percent by weight of a butadiene-acrylonitrile elastomer rubber. Further these polymers show excellent impact strength at low temperatures and are resistant to solvents used as blowing agents for refrigerator and freezer insulation.

    摘要: Elastomers are plasticized with a polymerizable monomer, in homogeneous admixture therewith, by adding the monomer to a latex of the elastomer, free of polymerization initiator, followed by coagulation of the monomer and polymer solids. The coagulated solids recovered from the latex may be compounded with a polymerization initiator for the monomer and a vulcanizing agent for the polymer and, optionally, an inorganic filler, and shaped into the desired product form. Polymerization of the polymer and vulcanization of the elastomeric polymer are initiated after shaping.

    摘要: Impact-resistant polymers which have low permeability to gases and vapors are prepared by polymerizing an olefinic nitrile, such as acrylonitrile, optionally with an acrylic ester, such as methyl acrylate, to at least about 70% conversion, and then introducing into the polymerization reaction medium a conjugated diene monomer, such as butadiene-1,3, and completing the polymerization reaction in the presence of said diene monomer.
