发明名称 MODIFIED ETHYLENE COPOLYMER
摘要 PURPOSE:To obtain a copolymer vulcanizable with sulfur, by modifying an ethylene copolymer comprising an ethylene unit as a main component, a (meth) acrylate unit, an acid anhydride group, a half ester group, etc., with an unsaturated amine or an alcohol. CONSTITUTION:An ethylene copolymer comprising a monomer unit shown by the formula I, 5-45mol% monomer unit shown by the formula II (R<1> is H or CH3; R<2> is 1-10C alkyl), and monomer units shown by the formula III and formula IV (R<3> is H or 1-10C alkyl), having 0.1-0.5wt% total amounts of the monomer units shown by the formula III and formula IV and a ratio of the unit shown by the formula III to the total amounts of >=99wt% is modified with (B) an unsaturated amine or unsaturated alcohol containing one or more double bonds. EFFECT:A vulcanized material having improved solvent resistance, weather resistance, ultraviolet light resistance, ozone resistance, heat resistance, low- temperature characteristics and rubber characteristics is obtained.
