Manufacture of poly(vinyl chloride). Yamada, Mamoru; Komaji, Takeshi; Nakajima, Takeji (Nippon Oils and Fats Co., Ltd., Japan). Japan. JP 51038752 B4 23 Oct 1976 Showa, 7 pp. (Japanese). (Japan). CODEN: JAXXAD. CLASS: IC: C08F014-06. APPLICATION: JP 68-75079 15 Oct 1968.In this article, certain chemicals are used. Some of their cas registry numbers are 26748-38-9 and 9002-86-2 DOCUMENT TYPE: Patent CA Section: 35 (Synthetic High Polymers) Vinyl chloride (I) was suspension-polymd. in the presence of tert-butyl peroxyneoheptanoate (II) [26748-38-9], tert-butyl peroxyneodecanoate (III) [26748-41-4], or tert-hexyl peroxyneodecanoate [62178-88-5] to give PVC [9002-86-2] with improved discoloration resistance. For example, neoheptanoyl chloride [15721-22-9] was treated with tert-butyl hydroperoxide [75-91-2] in the presence of NaOH to give II. In polymn. of 100 g I in the presence of 0.2 g III at 45.degree., the conversion was 66.5% (7 h), compared with 50% for polymn. using tert-butyl peroxypivalate. .

Kokai Tokkyo Koho JP 03269046 A2 29 Nov 1991 Heisei, 6 pp. (Japan). 21645-51-2 and 62178-88-5 are cas registry numbers. These chemicals are also mentioned in this article. CODEN: JKXXAF. CLASS: ICM: C08L031-00. ICS: C08F018-24; C08F220-20; C08F299-00. APPLICATION: JP 90-68327 20 Mar 1990. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) Section cross-reference(s): 38 The title compns. contain 10-60 parts prepolymers of diethylene glycol bis(allyl carbonate) (I) prepd. in the presence of a peroxide R1CMe2OOC(O)R2 (R1 = C1-5 alkyl; R2 = C4-12 tertiary alkyl), 0-30 parts I, 0-30 parts multifunctional (meth)acrylic acid derivs., and 10-90 parts inorg. fillers. Heating 1.5 kg I and 7.5 g tert-Bu peroxypivalate at 90° for 35 min gave a prepolymer (II) which was mixed (25 parts) with I 15, Al2O3 (particle size 5 mm) 60, and Bz2O2 0.8 part. Curing the mixt. between glass plates at 80° for 4 h gave a transparent marblelike sheet, vs. insufficient curing during 10 h when 40 parts I was used instead of 25 parts II and 15 parts I. .
