Abstract:
1408114 Semi-conducting polymer compositions UNION CARBIDE CORP 25 Sept 1973 [26 Sept 1972] 44904/73. Heading C3P Semi-conducting compositions comprise (1) a copolymer of ethylene with 2 to 5 weight per cent of ethyl acrylate or vinyl acetate, (2) 3 to 20 weight per cent of an ethylene/propylene/ termonomer elastomer and (3) 25 to 50 weight per cent of conducting carbon black. The termonomer from which the elastomer is derived may be 1,4 - hexadiene, dicyclopentadiene, methylcyclopentadiene or 5 - ethylidene bicyclo[2.2.1]hept-2-ene. The carbon black may be an oil furnace or acetylene black. The compositions may also contain conventional ingredients and may be used as insulation shielding compositions for power conductors.
