PROCESS FOR PREPARING PROPYLENE POLYMERS HAVING LONG CHAIN BRANCHES

The present invention relates to a process for the preparation of long chain branched propylene polymers via a polymerization of propylene, preferably under slurry or bulk conditions, in the presence of a catalyst system comprising a supported bridged metallocene catalyst and at least one alpha,omega-diene compound. The invention moreover relates to long chain branched propylene polymers obtained by the present process.
