Hollow molded polyesters: Hollow molded polyesters. Inata, Hiroo; Matsubayashi, Tohru (Teijin, Ltd., Japan). Japan. JP 52003644 B4 12 Jan 1977 Showa, 6 pp. (Japanese). (Japan). CODEN: JAXXAD. CLASS: IC: C08L067-02. APPLICATION: JP 75-77546 25 Jun 1975. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Fabrication and Uses) Bottles with improved transparency were prepd. by injection molding a blend of a polyester (contg. ethylene glycol units, terephthalic acid units, and 3-50 mol% isophthalic acid (I) or neopentylene glycol units) contg. 0.01-3% calcium stearate (II) [1592-23-0], glycerol trilaurate [538-24-9], glycerol tristearate [555-43-1], barium stearate [6865-35-6], pentaerythritol tetrastearate [115-83-3], or Na stearate [822-16-2]. Thus, a blend of a polymer [25135-73-3] (prepd. by transesterifying 165 parts dimethyl terephthalate with 29 parts dimethyl isophthalate and 130 parts ethylene glycol and polycondensing the resulting compn.) contg. 555-43-1 and 25135-73-3 are also in the experiment. 0.3% II was injection molded at cylinder temp. 236-70.degree. and die temp. 60.degree. to give a bottle with good transparency. .

CLASS: IC: C08L069-00. PRIORITY: US 76-702281 2 Jul 1976. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Fabrication and Uses) Esters of C6-36 alkanoic or alkanedioic acids with C2-21 (perfluoroalkyl)carbinols, neopentyl glycol derivs., pentaerythritol, or (HOCH2)2C(R1)ZC(R2)(CH2OH)2 (R1,R2 = C1-4 alkyl, CH2OH; Z = alkylene, oxydialkylene) are internal parting agents for molding of polycarbonates. Thus, bisphenol A-phosgene copolymer [25971-63-5] contg. 0.3% pentaerythritol tetrastearate (I) [115-83-3] has yellowing index (ASTM D 1925) -0.2 and 6.9 at 315 and 371°, resp., and demolding force 679 kg/cm2, compared with 0.1, 10.4, and undemoldable resp., in the absence of I, and -0.4, 6.7, and 868, resp., with a silicone oil in place of I.
