Branched polypropylene |
| abstract |
Provided is a method for the production of a polypropylene comprising branches in the polymer backbone, which method comprises: (a) forming macromers from an olefin monomer; and (b) polymerising propylene in the presence of the macromers and a catalyst, under polymerising conditions which favour the incorporation of the macromers into the polypropylene backbone, to form a branched polypropylene; wherein the catalyst employed in step (a) comprises a metallocene catalyst which promotes a chain terminating PÂalkyl elimination reaction to form terminal unsaturated groups in the macromers. |
