    摘要： A unique polymerization process for producing rubbery polymers having excellent physical properties and processability and freed from a cold flow property at normal temperature. The process, which might be called ''''Hightemperature instantaneous-continuous polymerization process,'''' comprises bringing a mixture of conjugated diolefin having from 4 to 5 carbon atoms per molecule and a metallic lithium or an alkyllithium catalyst continuously into a reaction zone maintained at a temperature of from about 90* to 235*C. to give a polymer having a desired degree of branching from which the desirable properties mentioned above are derived.
