Investigations on the stability of linoleic acid in fused melts with polyethylene glycol 6000 and pentaerythritol tetraacetate

Investigations on the stability of linoleic acid in fused melts with polyethylene glycol 6000 and pentaerythritol tetraacetate. Froemming, K. H.; Simons, B. (Inst. Pharm., Freie Univ. Berlin, Berlin, Ger.). Dtsch. Apoth.-Ztg., 117(49), 2035-7 (German) 1977. CODEN: DAZEA2. DOCUMENT TYPE: Journal CA Section: 63 (Pharmaceuticals) Incorporation of linoleic acid [60-33-3] in melts with polyethylene glycol 6000 [25322-68-3] or pentaerythritol tetraacetate [597-71-7] provided no and unsatisfactory protection, resp., against peroxidn. of the fatty acid by atm. O during storage. The lack of protection was attributed to the partially amorphous character of the polyethylene glycol melt and the occurrence of pores and cracks in the pentaerythritol tetraacetate melt, each of which facilitated diffusion of O into the melt.

Plastic bearings

Plastic bearings. Ikeda, Hirosaka; Isomura, Akihiko; Kusubae, Yosuke (Sumitomo Electric Industries, Ltd., Japan). Japan. Kokai JP 53073242 29 Jun 1978 Showa, 4 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C08K005-10. APPLICATION: JP 76-134854 9 Nov 1976. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Fabrication and Uses) Thermoplastics contg. polyol fatty acid esters are useful as antifriction materials. Thus, a compn. of 93 vol.% Duracon M 90-02 and 7 vol.% pentaerythritol tetraacetate (I) [597-71-7] was extruded, pelletized, and injection molded to give a bearing having durability 250 h, compared with 100 h for a similar bearing contg. hydrocarbon lubricant oil in place of I.
