    摘要: A polycarboxydiene polymer is prepared by reacting a saturated polycarboxylic acid, anhydride, ester or acid halide with a polyhydroxydiene polymer having pendant and terminal hydroxy groups obtained from the reaction of 1 mole of a living polymer having a molecular weight of 500 to 10,000 which is prepared by reacting a conjugated diolefin or a mixture of the conjugated diolefin and a vinyl compound having the formula: CH2 CR1 R2 wherein R1 represents a hydrogen atom or an alkyl group and R2 represents an aryl group or a pyridyl group in the presence of sodium or lithium metal or an organo sodium or lithium compound with 0.5 mole to 2 moles of epichlorohydrin, epibromohydrin, epifluorohydrin, chlorobutylene oxide or bromobutylene oxide.
