Abstract
PURPOSE:To prepare a reactive liq. polyisoprene which is highly reactive and capable of forming, by itself or by its reaction with other various substances, products having excellent water resistance and low-temp. characteristics, by reacting a partially hydrogenated liq. polyisoprene having a hydroxyl end group with an epoxidizing agent. CONSTITUTION:The title liq. polyisoprene has at least one hydroxyl group at the end of a molecular chain and at least one epoxy ring inside a molecular chain per molecule. It can be obtd. by the following method: a liq. polymer consisting chiefly of structural units derived from isoprene and having at least one hydroxyl group at the end of its molecular chain per molecule is partially hydrogenated to give a partially hydrogenated liq. polymer having an unsatd. bond inside its molecular chain, which is reacted with an epoxidizing agent. The liq. isoprene polymer having a hydroxyl group at the end of a molecular chain can be obtd. by any known method.
