- Insulated wire or cable. Turbett, Robert J. (Union Carbide Corp., USA). U.S. US 4044200 23 Aug 1977, 5 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: H01B007-28. NCL: 174023000R. APPLICATION: US 72-312134 4 Dec 1972. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) A heat-resistant elec. wire or cable suitable for direct burial contains a low-d. 1-butene-ethylene copolymer (I) [25087-34-7] as the primary insulator and contains N-contg. compds. as Cu deactivating agents and tetrakis[methylene-3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate]meth ane (II) [6683-19-8] as antioxidant. Thus, an elec.-insulating compn. comprising I (d. 0.950) 98.8, TiO2 1.0, II 0.1, and N,N'-bis[.beta.-(3,5-di-tert-butyl-4-hydroxyphenyl)propionyl]hydrazine [32687-78-8] 0.1% (Cu deactivator), and waterproofing filler ( blend of petroleum jelly with polyethylene [9002-88-4] of d. 0.927) had a lifetime of 28 days at 120.degree., compared with 8 days for a com. std.

- Some oxidation characteristics of polypropylene. Frank, H. P. (Chem. Linz A.-G., Linz, Austria). J. Polym. Sci., Polym. Symp., Volume Date 1976, 57(Degradation Stab. Polyolefins), 311-18 (English) 1977. CODEN: JPYCAQ. DOCUMENT TYPE: Journal CA Section: 36 (Plastics Manufacture and Processing) The thermal and photochem. oxidn. and corresponding oxidative degrdn. of polypropylene (I) [9003-07-0] were studied under various conditions. Thermal oxidn. in the melt was followed by multiple extrusions, by detg. the induction period for and rate of O take-up (165-220.degree.); various sterically hindered phenol antioxidants were used. Long-term thermal oxidn. (150.degree. oven aging) was performed during 400 h and followed by detn. of the polymer properties, antioxidant concn., and antioxidant decompn. products; analogous tests were performed after exposing the I to .ltoreq.1000 h in boiling water. In photooxidn., the most effective wave length range in the near UV was at .apprx.312 nm, but even at 378 nm a small photodegrdn. effect was obsd. The soly. of various antioxidants and UV stabilizers was detd. in amorphous I, but reliable results were obtained only for tetrakis[methylene 3-(3',5'-di-tert-butyl-4-hydroxyphenyl)propionate] [6683-19-8] at 100-200.degree..
