Abstract
PURPOSE:To obtain easily a liquid polyisoprene, which is superior in reactivity, a compatibility and storage stability and with which a material superior in water resistance, low-temperature property, etc., is produced for specified purposes, by reacting a liquid isoprene polymer with a compound having an epoxy radical. CONSTITUTION:An isoprene polymer, which has, e.g., 50mol% or more 1,4-bondings and 50mol% or less 1,2- and/or 3,4-bondings, is reacted with H2O2 to form a liquid isoprene polymer (A). This polymer (A) mainly consists of structural units derived from the original isoprene polymer and has 1 or more OH-radicals per molecule at the ends of its molecular chain. Its number-average MW is 300-25000 and its OH- radical content is 0.1-10milli-equivalent. Next, component A is mixed with a compound (B) which has an epoxy-radical, such as glycidyl isocyanate compound, in a proportion of 0.6mol or more of component B per equivalent of the OH-radical in component A, and allowed to react with each other in the presence or absence of a solvent at 0-200 deg.C under ordinary pressure- 100kg/cm<2>G for 0.1-100hr. the title liquid polyisoprene which has 1 or more epoxy-radicals per molecule at the ends of its molecular chains and whose number-average MW is 400-26000 and epoxy equivalent is 100-13000 is thus obtained.
