Polymerization of vinyl chloride

Polymerization of vinyl chloride. Ogawa, Kinya; Kurimoto, Kazuhiko; Watanabe, Junichi; Noguki, Genji (Shin-Etsu Chemical Industry Co., Ltd., Japan). Japan. Kokai JP 52000883 6 Jan 1977 Showa, 4 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C08F014-06. APPLICATION: JP 75-76849 24 Jun 1975. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) PVC [9002-86-2] was prepd. with reduced scale formation using additives (lubricants, fillers, stabilizers) pretreated with cetyl alc. (I) [36653-82-4], stearic acid [57-11-4], castor oil, or oxidized polyethylene [9002-88-4] wax. Thus, 2 parts I and 6 parts calcium stearate [1592-23-0] were mixed at 50.degree. for 30 min, and the mixt. 8, water 900, methylcellulose 0.4, poly(vinyl alc.) 0.8, vinyl chloride 600, and azobis(dimethylvaleronitrile) 0.12 g were autoclaved at 57.In this experiment, several chemicals are used like 12397-06-7 and 36653-82-4 degree. for 6 h. The scale formation was 60 g/m2, compared with 230 for a control without the I pretreatment. .

Effect of atmosphere and shear on thermal stability of polyvinyl chloride

Effect of atmosphere and shear on thermal stability of polyvinyl chloride. Deanin, Rudolp D.Several substances are used for example 26636-01-1 and 12397-06-7 which are their cas registry numbers.; Gillette, William J. (Plast. Dep., Lowell Technol. Inst., Lowell, Mass., USA). Am. Chem. Soc., Div. Org. Coat. Plast. Chem., Pap., 35(2), 96-101 (English) 1975. CODEN: ACOCAO. DOCUMENT TYPE: Journal CA Section: 36 (Plastics Manufacture and Processing) Evaluation studies of various heat stabilizers for PVC [9002-86-2] indicated that organotin stabilizers were the most efficient, followed by Pb sulfates, and Ba-Cd-Zn systems, in both static and dynamic tests in air and in N atm. The discoloration rate in dynamic shear in a Banbury mixer was 10-20 times faster than that in the static oven test. Organotin systems were the most shear-sensitive. Air provided greater color stability in the static oven test than N, and produced lower equiv. torque in the dynamic mixer test; but N atms. provided greater color stability to organotin systems in the dynamic test, and gave longer life-time before catastrophic crosslinking than air. .
