Propylene based polymer useful for the production of stretched film for packaging, has defined melt index, m.pt. and half height width of the DSC melt peak

A propylene based polymer has a melt index (JIS K7210) of 1.0-20 g/10 min) and a m.pt. (Tm) measured using a differential scanning calorimeter (DSC) of 147-159 deg C in which the half-height width (HW) of the melt peak as measured by DSC is characterized. A propylene based polymer (I) has a melt ind...

Zusammenfassung:	A propylene based polymer has a melt index (JIS K7210) of 1.0-20 g/10 min) and a m.pt. (Tm) measured using a differential scanning calorimeter (DSC) of 147-159 deg C in which the half-height width (HW) of the melt peak as measured by DSC is characterized. A propylene based polymer (I) has a melt index (JIS K7210) of 1.0-20 g/10 min) and a m.pt. (Tm) measured using a differential scanning calorimeter (DSC) of 147-159 deg C in which the half-height width (HW) of the melt peak as measured by DSC is characterized by equation (1). HW
