摘要： A blow-molded multi-ply vessel having excellent physical properties and good appearance which comprises two or more kinds of thermoplastic resins, at least one of which is a thermoplastic polyester resin, said vessel having a multi-ply structure of three or more layers at least at the thin wall part of the body thereof and a single layer structure at least at the open end of the mouth part thereof, and at least the thin wall part of the body being biaxially orientated. The vessel is produced by sequently and alternatively injecting two or more kinds of molten thermoplastic resins into one mold with shifting injection timing from a molding machine having plural injection cylinders with one mold closing operation to form a multi-ply parison and then blow-molding the parison at an orientating temperature.

摘要： A thermosetting injection molding compound comprising a specific crystalline unsaturated polyester comprising (A) a crystalline unsaturated polyester of terephthalic acid/fumaric acid=5/5-1/9 by mol (acid component) and 1,4-butanediol/other glycol=7/3-10/0 (glycol component) and (B) a styrene type monomer and/or allyl type monomer, and having specific ranges of a viscosity, a melting point and an acid value, said crystalline unsaturated polyester resin being admixed with (C) a glass fiber and (D) other additives in a specific ratio. The thermosetting injection molding compound has no tackiness and has excellent flowability and mold filling properties and can give an excellent molded product having good appearance without flow marks, surge or the like, and hence, the thermosetting injection molding compound of the present invention is particularly suitable for the preparation of electric, electronic and automobile parts which require excellent heat resistance, electrical characteristics and fire retardant properties.
摘要翻译：一种包含特定结晶不饱和聚酯的热固性注射模塑料，其包含（A）对苯二甲酸/富马酸的结晶不饱和聚酯= 5 / 5-1 / 9摩尔（酸组分）和1,4-丁二醇/其它二醇= 7 / 3-10 / 0（二醇组分）和（B）苯乙烯型单体和/或烯丙基类单体，并具有粘度，熔点和酸值的特定范围，所述结晶不饱和聚酯树脂与（ C）玻璃纤维和（D）其他特定比例的添加剂。热固性注射成型化合物没有粘性并具有优异的流动性和模具填充性，并且可以得到具有良好外观的优异的模制产品，没有流痕，浪涌等，因此本发明的热固性注射模塑料特别适合用于制备需要优异耐热性，电气特性和阻燃性能的电气，电子和汽车部件。
