Polyester compositions

Polyester compositions. (Diafoil Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 59172542 A2 29 Sep 1984 Showa, 10 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C08L067-00; C08G063-22; C08K003-00; C08K005-09. APPLICATION: JP 83-48148 23 Mar 1983. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) Compns. suitable for high-speed film casting with static charge application comprise a polyester, 0.05-1% (based on polyester) alk. earth salt of a polyester oligomer, and 0.01-0.5 mol% (based on acid components) polyester-sol. K, Mg, and/or Mn compd. Thus, a mixt. of di-Me terephthalate 100, HOCH2CH2OH 60, and Ca(OAc)2.H2O 0.095 part was heated at 230° for 4 h. Terephthalic acid (0.05 part) was added to the mixt., which was heated at 230° for 20 min. AcOK [127-08-2] (0.03 mol%, based on acid components), 0.7 equiv Et acid phosphate [37203-76-2] (based on AcOK), and 0.035 part Sb2O3 were added to the mixt., which was heated for 4 h to give a polyester having intrinsic viscosity 0.65 and melt resistivity 3.4 ′ 107 W-cm.

Rust-removing and corrosion-preventing composition for iron surfaces. Foldi Polyak, Klara; Janaszik, Fereno; Liszi, Janos; Meszaros, Lajos; Farkasdy, Iva; Miskolczi, Istvan (Elso Vegyi Industria Szovetkezet, Hung.). Hung. Teljes HU 26683 O 28 Sep 1983, 10 pp. (Hungarian). (Hungary). CODEN: HUXXBU. CLASS: IC: C23F011-16; C23G001-06; C09K013-06. APPLICATION: HU 81-1853 24 Jun 1981. DOCUMENT TYPE: Patent CA Section: 55 (Ferrous Metals and Alloys) An aq. soln., for simultaneous derusting and temporary corrosion protection of Fe surfaces for adhesion of paint contains mono- and/or di-C2-5-alkyl ester of H3PO4 10-50, preferably 10-25, optionally H3PO4 0-25, inactive trialkyl phosphate ￡12.5, CaCO3 0.05-0.25, K bichromate 0.02-0.1, hexamethylenetetramine [100-97-0] 0. 37203-76-2 and 100-97-0 are cas registry numbers of chemicals which are used as reagents here.1-0.5, and Zn(NO3)2 0.2-1%. Thus, an aq. soln. contg. Et phosphate [37203-76-2] 40, pentyl phosphate [2382-76-5] 8, EtOH 10, corrosion inhibitor soln. of CaCO3 8, K bichromate 3, hexamethylenetetramine 10, Zn(NO3)2 25 g/L 20, and H2O 22% was used to coat a cold-rolled steel strip by dipping, washing after 10 min, and air-drying. No rust was obsd. after 240 h in air and 100% adhesion of Zn chromate paint after 24 h holding in water vapor. Similar data were obtained for Bu phosphate [126-73-8], iso-PrOH, and H3PO4 addn. .
