  • Patent number: 4767806
    Abstract: The invention relates to a novel low profile additive (LPA) for uncured polyester resins and the resultant molding compositions. The low profile additive is the reaction product of an ethylene/alphaolefin copolymer with a carboxylic acid or anhydride, to thereby form a non-thermoplastic carboxyl modified polyolefin. The novel LPA is a remarkably effective dimensional stabilizer and has displayed the ability to achieve net expansion in a cured polyester resin molding composition.

  • Patent number: 4260541
    Abstract: The invention relates to the method for producing internally plasticized poly(vinyl chloride) suitable for the purposes of earth insulation and medical care. The production method according to the invention consists in the polymerization or copolymerization of vinyl chloride in an aqueous dispersion medium in the presence of up to 50 weight %, related to vinyl chloride, of a polymeric plasticizer prepared by polyesterification of dicarboxylic acids and diols. If desired, the polymerization can be carried out also in the presence of up to 12 weight % of alkyl esters of cyanuric acid and/or the copolymer of ethylene with vinyl acetate as the stabilizers of polymer-chain structure. The polymerization is carried out to the conversion of vinyl chloride 55 to 94% at temperature -20.degree. to +80.degree. C. in the presence of an emulsifier and the resulting polymer is isolated and worked up in the known way.
