  • Polyester resinous composition, molded articles and process for preparation thereof
    Patent number: 4461871
    Abstract: A polyester resinous composition comprising (a) an aromatic polyester, (b) a copolymer of an .alpha.-olefin and a glycidyl ester of .alpha.,.beta.-ethylenically unsaturated carboxylic acid and (c) an ethylene based copolymer of ethylene and .alpha.-olefin having more than three carbon atoms. The composition has highly improved impact strength at low temperature and good flow properties upon injection molding. The composition can be molded to form various articles by conventional molding methods.
    Type: Grant

  • Polyethylene terephthalate molding compositions
    Patent number: 4284540
    Abstract: Impact-modified and moldability-improved polyethylene terephthalate molding compositions are provided which comprise polyethylene terephthalate resins, a copolymer of .alpha.-olefins and glycidyl esters of .alpha.,.beta.-ethylenically-unsaturated carboxylic acids and barium salt of fatty acids. Glass fiber reinforcement of the polyester compositions is preferable because of further enhancement of the moldability of the polyester composition thereof. In addition, resistance to moist heat is also increased.
