| abstract |
The present invention relates to a process for the production of propylene homo- and copolymers having a broad molecular weight distribution and a low ash content, with “ash” denoting aluminium as well as residues of catalyst, cocatalyst or any additive, such as titanium (Ti) or 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, meltblown nonwovens. |
