Abstract

A polypropylene having a melt flow rate MFR2 (230° C.) of at least 20 g / 10 min; and a Mw / Mn ratio of at least 15.0.

Description

technical field [0001] The present invention relates to a novel polypropylene having an extremely broad molecular weight distribution and to its manufacture. Background technique [0002] Polypropylene is used in many applications. Depending on its end application, the properties of polypropylene must be adjusted accordingly. For example very high stiffness and fluidity are required for some end applications. [0003] WO 2011076611 A1 describes multiphase systems. The product however has low flow and moderate stiffness. [0004] WO2010 / 089123 A1 defines the melt flow rate MFR 2 (230°C) Polypropylene material up to 12g / 10min. The molecular weight distribution (Mw / Mn) is not more than 8. [0005] WO2011 / 117103 describes propylene copolymers with rather low stiffness. The melt flow rate is very low. [0006] Therefore, there is still a need to provide polypropylene materials with excellent high stiffness and high fluidity. Contents of the invention [0007] The findi...
