PROBLEM TO BE SOLVED: To provide an ethylenically unsaturated copolymer which is excellent in weather resistance, heat resistance and ozone resistance, has a high vulcanization rate and is excellent in scorch stability. SOLUTION: An ethylenically unsaturated copolymer obtained by copolymerizing a novel and useful linear triene compound represented by the following formula (1) with an α-olefin. Embedded image (R 1 to R 6 are each independently a hydrogen atom or carbon atom 1 An alkyl group having 1 to 3 carbon atoms, R 7 is an alkyl group having 1 to 3 carbon atoms, n is an integer of 0-5. However, when n is 2 or more, R 4 and R 5 may be the same or different. ) |
