    摘要： A process for polymerization of a diene is provided. The process comprises: a) reacting the diene with hydrogen peroxide in a hydrophilic organic solvent in the presence of water to obtain a polymerization reaction mixture; b) contacting the polymerization reaction mixture with water having a temperature of from 20 to 80° C. to form a mixture having an organic phase and an aqueous phase; c) removing unreacted gaseous diene from the water mixture obtained in b); d) separating the aqueous phase comprising the hydrophilic solvent from the organic phase of the water mixture; and e) distilling volatile materials from the separated organic phase from d) to obtain the polymerization product; wherein a temperature of the reaction a) is from 50-150° C., a pressure of the reaction a) is from 0 to 50 bar, the unreacted gaseous diene removed in c) is condensed, distilled and the distillate obtained reacted according to a), and the hydrophilic solvent is recovered from the separated aqueous phase and reused according to a). Also provided is an apparatus for conducting the process of the invention.
