Heat- and weather-resistant synthetic resin compositions

Heat- and weather-resistant synthetic resin compositions. Iwamoto, Kyoichi; Kakei, Hiroshi (Tokuyama Soda Co., Ltd., Japan). Japan. Kokai JP 52033932 15 Mar 1977 Showa, 8 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C08K003-22. APPLICATION: JP 75-110313 10 Sep 1975. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) Heat- and weather-resistant synthetic resin compns. contain stabilizers prepd. from cinnamic acid (I) [621-82-9]-modified epoxy resins and metal compds. Thus, a mixt. of 35 g epoxy resin and 15 g I was heated 10 hr at 200.degree. to give a white viscous product which was cooled to 0.degree., powd., mixed (100 parts) with 12.5 parts calcium stearate [1592-23-0] at .apprx.0.degree., and heated 1 h at 60.degree.. A mixt. of PVC [9002-86-2] 100, Ca-Zn stabilizers 3, epoxidized soybean oil 2, octyltin mercaptide 1, stearic acid 0.3, waxes 0.5 part and this compn. 1.125 parts was kneaded 4 min at 80.degree. to give sheets which were combined and pressed at 180.degree., giving a sheet with improved heat- and weather resistance compared with a control when the modified epoxy resin compn. was omitted.

Food antifoam agent

Food antifoam agent. Sakakibara, Sakuichi; Sugisawa, Ko; Matsui, Fumio; Nakajima, Setsuo (House Food Industrial Co., Ltd., Japan). Japan. Kokai JP 52068883 8 Jun 1977 Showa, 7 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: B01D019-04. APPLICATION: JP 75-144958 8 Dec 1975. DOCUMENT TYPE: Patent CA Section: 17 (Foods) Antifoam agents for food industries contain 1 part Ca or Mg salts of fatty acids and 0.4-30 parts edible fats and(or) fatty acids. Thus, a mixt. of 10 kg Ca stearate [1592-23-0] and 10 kg hardened tallow was heated at 70.degree. for 10 min and cooled to room temp. The solid obtained was pulverized to yield 20 kg powd. antifoam. When the antifoam (0.025 g) was added to 700 mL Tonyu (soybean protein soln.) and the mixt. heated to boiling, practically no foam was obsd.
