Stabilized surface-modified fillers

Stabilized surface-modified fillers.Some chemicals with cas registry numbers like 97-65-4 and 9003-79-6 are also used. Ferrigno, Thomas H. (USA ). U.S. US 4420341 A 13 Dec 1983,12 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C09C001-42. NCL: 106308000Q. APPLICATION: US 82-365673 5 Apr 1982. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) Section cross-reference(s): 39 Inorg. filler surfaces are modified (by mixts. of unsatd. or satd. org. acids and stabilized by antioxidants or liq. agents, the acids being reactive with the fillers) to give greater compatibility with and strength to the matrix than is the case for untreated fillers. Thus, 100-400 g ground oyster shell filler was preheated 1 h at 225°F in a blender, and a mixt. of linseed oil fatty acids 0.67, mineral oil 0.33, and 2,6-di-tert-butyl-p-cresol [128-37-0] 0.02% was added and mixed 10 s. The filler had initial oil absorption of linseed oil 15.4 and after 7 days 15.2, initial packing factor 0.694 and after 7 days 0.697. .

Stabilization of plasticized poly(vinyl chloride) by phenolic compounds

Stabilization of plasticized poly(vinyl chloride) by phenolic compounds. Abdullin, M. I.; Zueva, N. P.; Kirilovich, V. I.; Minsker, K. S. (USSR). Plast. Massy, (1), 15-17 (Russian) 1984. CODEN: PLMSAI. ISSN: 0554-2901. DOCUMENT TYPE: Journal CA Section: 37 (Plastics Manufacture and Processing) The effect of the concn. of di-Bu, diisooctyl, dioctyl, didodecyl, and diisotridecyl phthalate plasticizers on the oxidative thermal dehydrochlorination of PVC [9002-86-2] stabilized with bisphenol A [80-05-7] or 4-methyl-2,6-di-tert-butylphenol [128-37-0] antioxidants was studied. The min. dehydrochlorination rate (v) of plasticized PVC was attained at 1 ′ 10-3 mol antioxidant/mol PVC.Several substances with their cas registry numbers 80-05-7 and 9002-86-2 may be metioned in this study. The crit. concn. of the antioxidant did not depend on the plasticizer nature. The v at a const. antioxidant concn. decreased continuously with increasing plasticizer content. The min v depended on the plasticizer nature, i.e., on its oxidative stability. The inhibiting effect of the phenolic antioxidants increased with increasing oxidn. rate of the plasticizer. The oxidative stability of the plasticizers must be considered in stabilization of plasticized PVC with phenolic antioxidants. .
