PRIORITY: DD 83-251193 24 May 1983. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) An oligomer or polymer of a quinoline deriv. and a phenolic thio compd. are mixed with polyethylene (I) [9002-88-4] to give compn. which have good processability, are radiochem. crosslinkable, and are useful as coverings for moderate-voltage elec. cables. Thus, I was mixed with 0.12% 1,2-dihydro-2,2,4-trimethylquinoline oligomers and 0.015% 4,4'-thiobis(2-tert-butyl-6-methylphenol) [96-66-2] at 290° and used as a covering for a 20-kV cable. The tensile strength and break elongation of the covering was unchanged after 10 days at 135°.

Antioxidants and stabilizers. LXIX. Effect of products of the oxidation transformation of 4,4'-thio-bis(2-methyl-6-tert-butylphenol) on the oxidation of tetralin. Jirackova, L.; Pospisil, J. (Inst. Macromol. Chem., Czech. Acad. Sci., Prague, Czech.). Angew. Makromol. Chem., 70, 135-43 (English) 1978. CODEN: ANMCBO.In this experiment, several chemicals are used like 96-66-2 ISSN: 0003-3146. DOCUMENT TYPE: Journal CA Section: 36 (Plastics Manufacture and Processing) Section cross-reference(s): 22 The influence of oxidn. products from 4,4'-thiobis(2-tert-butyl-6-methylphenol) (I) [96-66-2] antioxidant for polyolefins on oxidn. at <150° was studied in Tetralin (II) [119-64-2], since O absorption in polyolefins at such temps. is very slow and accurate measurements cannot be obtained. AIBN-initiated oxidn. of II at 60° and II hydroperoxide-initiated oxidn. at 120° were detd. Nearly all of the S-contg. oxidn. products exhibited antioxidative activity. Their formation under conditions which inhibit the autoxidn. of polyolefins and their effectiveness under different initiation conditions indicate that antioxidants contg. a sulfide group can inhibit oxidn. by 2 different mechanisms and that the oxidn. products of the antioxidant participate in the autoxidn. The antioxidative activity of thiobisphenol-type compds. is lost only after total conversion to quinoid-type products or to sulfones. .
