Abstract

1392725 insulated conductors GENERAL ELECTRIC CO 13 June 1972 [16 July 1971] 27664/72 Heading H1A [Also in Divisions C3. and B2] Cu or A1 electric conductors are coated with a cresol solution of a polyimide (P), the cresol then being driven off by heat, after which the polyimide is cured, e.g. by heating to 150-300‹ C., with or without curing accelerators. The coating of (P) may be further coated with polyamides, polyesters, silicones, polyvinyl formal resins, epoxy resins, polyimides, or P.T.F.E. (P) has formula where X is H or CH 3 , R is a C 1-40 hydrocarbon radical, -CH 2 CH-O-CH 2 CH 2 – or a group consisting of 2 aryl residues, optionally substituted by halogen, joined by C 1-10 alkylene, -S-, -SO 2 -, -CO-, or -O-; R1 is organic; and n = 2-10,000.
