Title: Process for preparing a polymerizable diene polymer

Abstract: A polymerizable diene polymer is prepared by reacting a polymerizable unsaturated carboxylic acid, anhydride, ester or acid halide with a polyhydroxydiene polymer having terminal and pendant hydroxy groups obtained from the reaction of one 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 said conjugated diolefin and a vinyl compound having the formula: CH.sub.2 = CR.sub.1 R.sub.2 wherein R.sub.1 represents a hydrogen atom or an alkyl group and R.sub.2 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 2.0 moles of epichlorohydrin, epibromohydrin, epifluorohydrin, chlorobutylene oxide or bromobutylene oxide.
