CODEN: FRXXBL. CLASS: IC: C08F255-02; C08F004-38; C08J003-24. APPLICATION: FR 82-18778 9 Nov 1982. DOCUMENT TYPE: Patent CA Section: 35 (Chemistry of Synthetic High Polymers) Crosslinkable polymers are prepd. by grafting unsatd. silanes on polyolefins in the presence of tert-Bu cumyl peroxide [30580-75-7], esp. during extrusion.

Crosslinked polyolefin electric cables

Crosslinked polyolefin electric cables. (Showa Electric Wire and Cable Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 59087709 A2 21 May 1984 Showa, 4 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: H01B013-14; C08K005-14; C08K005-36; C08L023-00. APPLICATION: JP 82-197038 10 Nov 1982. DOCUMENT TYPE: Patent CA Section: 38 (Plastics Fabrication and Uses) A mixt. of 100 parts polyolefin compn., 0.5-7 parts liq. crosslinking agents composed of 10-90% tert-Bu cumyl peroxide (I) [30580-75-7] and 10-90% dicumyl peroxide (II) [80-43-3], and liq. aging inhibitors (5-40% of the crosslinking agents) is extrusion coated on a conductor and then heated for crosslinking. The manufd. cables have excellent elec. properties and aging resistance. Thus, a mixt. of polyethylene [9002-88-4] 100, II 1, I 1, and bis[2-methyl-4-(3-n-alkylthiopropionyloxy)-5-tert-butylphenyl] sulfide 0.2 part was extrusion coated on a conductor. The coating had excellent heat-aging resistance.
