Polypropylene with living hinge properties

摘要

The present invention relates to a polypropylene which has - a melt flow rate MFR(230°C, 2.16 kg) of at least 13 g/10 min, - an amount of xylene solubles XS of 6.0 wt% or less, and - a crystalline fraction, wherein at least 10 % of the crystalline fraction melts the temperature range of from 160 to 170°C, as determined by the stepwise isothermal segregation technique (SIST).
