摘要:
A flame retarding thermoplastic polyester composition superior in thermal stability, fluidity and mechanical properties, and prepared by mixing (a) halogen containing polystyrene and/or halogen containing poly-.alpha.-methylstyrene, (b) antimony trioxide and (c) epoxy compound with respect to thermoplastic polyester is disclosed.
摘要:
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.
摘要:
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.
