<p>Diene polymers of 10,000 to 1,000,000 in weight-average molecular weight measured according to GPC, represented by general formula (I), wherein D1 represents a diene polymer, R1 represents an active hydrogen-free organic group containing 1 to 20 carbon atoms or a silicon compound, m represents 0 or an integer of 1 to 6, and n represents 0 or an integer of 1 to 6, provided that m is 1 or more when n = 0 and n is 2 or more when m = 0. These diene copolymers are used as a curable rubber composition suited for preparation of tires including tire treads, as an agent for enhancing toughness of high-impact polystyrene, etc., or as a thermoplastic elastomer or thermoplastic resin.</p> |
