摘要： Process for the manufacture of a branched polypropylene having a branching index g' of less than 1.00, wherein the process comprises the step of polymerizing propylene and optionally another (other) comonomer(s) under non-supercritical conditions in a reaction vessel, characterized in that a. the pressure during the polymerization of propylene and optionally another (other) comonomer(s) in said reaction vessel is a at least 45,4 bar, b. the temperature during the polymerization of propylene and optionally another (other) comonomer(s) in said reaction vessel is below 90 °C and c. the polymerization of propylene and optionally another (other) comonomer(s) is conducted in said reaction vessel in the presence of a catalyst system having surface area of not more than 350 m2/g measured according to ISO 9277 and said catalyst system comprises a metallocene catalyst having zirconium as the transition metal.

摘要： A polymer composition useful in making products produced by extrusion, molding, film and thermoforming processes, comprises optionally a matrix polymer, a nanofiller, and a polyolefin with functional groups that has been prepared directly by polymerizing olefin monomers with comonomers comprising functional groups using a single site catalyst. An independent claim is included for a use of a polyolefin with functional groups that has been prepared directly by polymerizing olefin monomers with comonomers comprising functional groups using a single site catalyst as a compatibilizer in a polymer composition comprising optionally a matrix polymer and a nanofiller.
