1,3-pentadiene is polymerized from a mixture of saturated and unsaturated hydrocarbon compounds, the compounds having primarily 5 carbon atoms per molecule, with an anionic polymerization initiator. The mixture of saturated and unsaturated hydrocarbon compounds is contacted, in an inert atmosphere, with an anionic polymerization initiator to form a reaction mixture. The anionic polymerization initiator is present in an amount sufficient to inactivate polymerization-terminating compounds present in the mixture and to initiate polymerization of 1,3-pentadiene from the mixture. The reaction mixture is heated with stirring to a temperature sufficient to inactivate the polymerization terminating compounds. After inactivation of the polymerization terminating compounds, the reaction mixture is then heated with stirring to a temperature sufficient to initiate polymerization of 1,3-pentadiene from the reaction mixture. Polymer recovery and subsequent functionalization, if any, follow thereafter.
