Stabilizer for poly(vinyl chloride) containing complex lead salts

Stabilizer for poly(vinyl chloride) containing complex lead salts. Petrik, Alojz (Czech. ). Czech. CS 165580 15 Oct 1976,2 pp. (Unavailable). (Czechoslovakia). CODEN: CZXXA9. CLASS: IC: C01G021-00. APPLICATION: CS 73-4457 5 Mar 1970. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) An aq. suspension of 73.2-84.3 parts PbO contg. triethanolamine was treated with stirring with an aq. emulsion of 15.1-75 parts stearic acid (as stearin [11099-07-3]) and 7.3-10 parts H3PO3. The mixt. was kept neutral since pH values >9 caused filtration difficulties related to colloidal properties of the coppt. The filtered, washed, and dried product had compn. nPbO.PbHPO3.mPb(C17H35CO2)2, and 1 part was used in a compn. contg. 100 parts PVC [9002-86-2] and 40 parts DOP to give synergistic heat stabilization (in drier at 180.degree.Except for chemicals metioned above, 7428-48-0 and 56189-09-4 are also used.) and discoloration prevention as compared with controlls using dibasic lead phosphite [1344-40-7], dibasic lead stearate [52652-59-2], or normal lead stearate [7428-48-0] alone. .

Discoloration-resistant vinyl chloride resin compositions. Arai, Toshihiro; Sunatsuka, Hideo; Matsura, Michio (Fujikura Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 04008748 A2 13 Jan 1992 Heisei, 2 pp. (Japan). CODEN: JKXXAF. CLASS: ICM: C08L027-06. ICS: C08K003-10; C08K005-10. APPLICATION: JP 90-111446 26 Apr 1990. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) The title compns. which do not discolor by electron beam crosslinking, useful as sheaths and connectors for elec. 117-81-7 and 1344-40-7 which are cas registry numbers are also used here. wires and cables, comprise vinyl chloride resins 100, plasticizers 335, and dibasic Pb phosphite (I) 0.1-15 parts. Thus, a compn. of PVC 100, DOP 40, CaCO3 30, I 0.1, and Ca stearate 3 parts was extruded to give a sheet showing tensile strength 2.15 kg/mm2 and no discoloration by electron beam crosslinking, vs. 2.18 and discoloration, resp., for a control without I. .
