<p>The present application relates to a method for manufacturing a propylene polymer, including the following steps: a) fermenting and optionally purifying first renewable materials to produce an alcohol or an alcohol mixture, said alcohol or alcohol mixture including at least isopropanol and/or at least a mixture of ethanol and 1-butanol; b) dehydrating the resulting alcohol or the alcohol mixture with a view to producing an alkene or alkene mixture in a first series of reactors, said alkene or alkene mixture containing at least propylene, and optionally purifying the alkene mixture to obtain propylene; c) polymerizing the propylene in a second reactor, optionally in the presence of a comonomer, so as to produce a propylene polymer; d) isolating the propylene polymer obtained in step c); and e) grafting the propylene polymer obtained from step d). The invention also relates to the grafted propylene polymer capable of being obtained by said method, to the compositions containing said polymer, as well as to the uses of said polymer.</p> |
