Abstract:
1. Polypropylene comprising: (a) a melting temperature (T (b) a melt flow rate MFR (c) a xylene cold soluble fraction (XCS) measured according to ISO 6427 at 23° C. of not more than 1.5 wt-%, (d) a number average molecular weight (Mn) measured according to ISO 16014-4:2003 of not more than 110 kg/mol and wherein said polypropylene further has (e2) <2,1> regiodefects of equal or more than 0.4 mol-% determined by and (e1) a melting temperature (T and/or (e3) 45.0 to 67.0 wt-% of a crystalline fraction having a lamella thickness in the range of 7.70 to 14.09 nm wherein said fraction is determined by the stepwise isothermal segregation technique (SIST), and/or (e4) 18.0 to 50.0 wt-% of a crystalline fraction having a lamella thickness of more than 14.09 nm wherein said fraction is determined by the stepwise isothermal segregation technique (SIST).
