PURPOSE:The titled polymer which can form a cured product excellent in rubber elasticity and dynamic properties by reaction with an epoxy resin, an organic polyisocyanate compound, or the like, having a specified structural formula. CONSTITUTION:A halogen-terminated liquid diene polymer of formula I (wherein X is a halogen and n is 6-450). A conventional liquid diene polymer shows fluidity at room temperature and, when cured, it forms a three-dimensional network structure which shows physical properties like those of a vulcanized rubber. Though it is useful as a cross-linking agent for polymers containing a long- chain diamine or double bonds, the rubber elasticity or physical properties of such a cured product has been unsatisfactory. By the incorporation of terminal halogen atoms, the diene polymer can form a cured product excellent in rubber elasticity and dynamic properties and used as a resin modifier, raw material for a cured product or the like. This polymer is produced by reacting a hydroxyl group-terminated liquid diene polymer of formula II with a halogen compound.
