Abstract
A process for the production of semifinished products and/or molded components from polypropylene by grafting thereto an alkoxysilane compound in the presence of an organic peroxide involves mising the polypropylene, the silane compound, and the peroxide and subsequently plasticizing and extruding at a temperature of about 170.degree.-240.degree. C. The process utilizes an essentially isotactic homopolymer of propylene with a density of about 0.90-0.91 g/cm.sup.3 and a melt index MFI (#.degree. C./5 kp) of smaller than 0.7 g/10 min, preferably smaller than 0.1 g/10 min, and with a molecular weight higher than 5.multidot.10.sup.5. An initially non-crosslinked semifinished product is obtained.
