Abstract
A process of producing from a hydrocarbon diolefin conjugate polymer chains containing terminal hydroxyl units comprising the polymerization of a conjugated diolefinic hydrocarbon containing 4-8 carbon atoms in the presence of an initiator selected from the group consisting of lithium metal and organolithium compounds the termination of the active polymer thus formed by reaction with a terminating agent selected from the group consisting of epoxidized mono-olefinic hydrocarbons and compounds having the formula r1 r2 c = o in which r1 and r2 are selected from the group consisting of hun radical phenyl and hydrocarbon alkyl radicals and the contact of the product of said termination reaction with an agent that yields protons.
