| description | The present invention relates to a process for making low ash propylene homo- or copolymers with improved properties, with "ash" denoting aluminium as well as residues of catalyst, cocatalyst or any additive, such as titanium (Ti) and silicium (Si) derivatives, used in the production of propylene polymers. The propylene polymers of the present invention are useful to make films, such as capacitor films, as well as fibers and nonwovens, such as for example staple fibers, spunbond nonwovens or meltblown nonwovens. |
