1,3-pentadiene is polymerized from a mixture of saturated and unsaturated hydrocarbon compounds, the compounds having mainly 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 the polymerization stop compounds, which are present in the mixture, as well as to initiate the polymerization of 1,3-pentadiene from the mixture. The reaction mixture is heated by stirring to a temperature sufficient to inactivate the end-of-polymerization compounds. After inactivation of the end-of-polymerization compounds, the reaction mixture is subsequently heated while stirring to bring it to a sufficient temperature which makes it possible to initiate the polymerization of 1,3-pentadiene from the reaction mixture. The recovery of the polymer and the possible functionalization come next. |
