摘要： 1,257,592. Cross-linking olefin polymers. MONTECATINI EDISON S.p.A. 27 May, 1970 [29 July, 1969], No. 25465/70. Heading C3P. [Also in Division C2] Elastomers or plastomers, such as polyethylene or ethylene/propylene copolymers are crosslinked or vulcanized by heating at 150 to 170 C. for from 5 to 15 minutes in the presence of, as cross-linking or vulcanizing agent, a compound of the Formula I where R 1 is a cycloalkyl, aryl or heterocyclic radical, each of which may be alkyl or halogen substituted, R 2 is a hydrogen atom or an alkyl aryl or cycloalkyl radical, each of which may be optionally alkyl or halogen substituted or R 1 and R 2 together with the carbon atom to which they are attached form a cycloaliphatic ring which may be alkyl, aryl, aralkyl, alkylidene or arylalkylidene substituted, R 3 and R 4 are each a hydrogen atom or an alkyl, aryl or cycloalkyl radical any of which may be alkyl or halogen substituted, or R 3 and R 4 together may form a cycloaliphatic ring which may be alkyl, aryl, aralkyl, alkylidene or arylalkylidene substituted, R 5 and R 6 are each an alkyl, aryl, aralkyl or cycloalkyl radical any of which may be alkyl or halogen substituted. A preferred composition comprises in parts by weight ethylene/propylene copolymer 100, carbon black 10-80, zinc oxide or magnesium oxide 1-10, sulphur 0À15-0À5, compound I 0À005-0À02 mols.
