PURPOSE: The titled copolymer which can give a vulcanizate excellent in heat resistance, solvent resistance, weather resistance, ultraviolet ray resistance, O 3 resistance, low-temperature properties, rubbery properties and hardness, obtained by modifying a specified ethylene copolymer with an unsaturated amine or an unsaturated alcohol. n CONSTITUTION: The titled copolymer of a MI of 0.01W1,000g/10min is obtained by modifying an ethylene copolymer consisting of 50W94.9mol% unit derived from ethylene of formula I, 45W5mol% unit of formula II [wherein R 1 is H or CH 3 , X is one of the groups of formulas IIIWV (wherein R 2W3 are each a 1W10C alkyl, R 4 is a 1W4C alkylene and R 5 is a 1W4C (alkoxy)alkyl], an acid anhydride group-containing radical-polymerizable monomer of formulas VI, VII or the like, or 5W0.1mol% unit derived from COOH-containing radical- polymerizable monomer of formula VIII (wherein R 7 is R 1 ) with a modifier comprising an unsaturated amine or unsaturated alcohol having at least one C=C double bond other than an aromatic double bond. If desired, this copolymer is vulcanized with at least one vulcanizer selected from among sulfur, a sulfur donor and a peroxide. n COPYRIGHT: (C)1986,JPO&Japio |
