Polyesters

Polyesters. (Toyobo Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 60088028 A2 17 May 1985 Showa, 10 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: ICM: C08G063-22. APPLICATION: JP 83-196603 19 Oct 1983. DOCUMENT TYPE: Patent CA Section: 35 (Chemistry of Synthetic High Polymers) Polyesters having good electrostatic adhesion and heat resistance contain Ca and/or Mg, P, and other metal compds., the P compds. being added in >2 portions. Thus, a polyester [25038-59-9] having max. casting speed (electrostatic adhesion) 48 m/min and change in intrinsic viscosity (IV) in 4 h at 300°/100 mm 0.170 was prepd. by adding Mg(OAc)2 [142-72-3] 100, NaOAc [127-09-3] 100, (MeO)3PO (I) [512-56-1] 7, and PhPO(OMe)2 (II) [2240-41-7] 14 ppm to the 1st esterification reactor for terephthalic acid and ethylene glycol and adding 31 ppm I and 62 ppm II to the 2nd esterification reactor. Adding 38 ppm I and 77 ppm II to the 1st esterification reactor gave a polyester with max. casting speed 38 m/min and change in IV 0.175.

Polyester containing internal granules

Polyester containing internal granules. (Toyobo Co., Ltd.; Nihon Magfan K. K., Japan). Jpn. Kokai Tokkyo Koho JP 60088029 A2 17 May 1985 Showa, 6 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: ICM: C08G063-22. ICA: C08L067-02; C08L069-00. APPLICATION: JP 83-196605 19 Oct 1983. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) Org. derivs. of alkali metals, alk. earth metals, Mn, Zn, Zr, and P are sprinkled on reaction mixts. for polyester manuf., and the product is used to prep. moldings having smooth surface and low content of fish eyes. Thus, adding magnesium acetate [142-72-3] 100, Na acetate [127-09-3] 100, tri-Me phosphate (I) [512-56-1] 9, and di-Me phenylphosphonate (II) [2240-41-7] 18 ppm through porous rings to the reaction mixt. of ethylene glycol (III) and terephthalic acid (IV), sep. adding 39 ppm I and 78 ppm II similarily to another III-IV reaction mixt., polymg., and combining the product mixts. gave polymer [25038-59-9], which provided a film having 8 fish eyes/100 cm2. When the compds. were added through a single pipe, the polymer gave a film having 100 fisheyes/100 cm2.
