Abstract:
A composition suitable for the manufacture of films having a very advantageous stiffhess-processability-balance comprising a high crystalline propylene polymer having a) T p of at least 122.5 °C and b) T w of at least 118 °C, whereby the T p and the T w are calculated from the temperature rising elution fractionation (TREF)-function of the propylene polymer in the range of 80 to 140 °C, wherein T p is the maximum temperature of the TREF-function; T w the weight average temperature of the TREF-function defined by formula (I) T i ; the temperature at which the concentration c i of an elute is determined; and c i the concentration of the elute at the temperature T i .
