ABSTRACT:
Polyolefin molding composition comprising of a polyolefin formed from an olefin having at least 3 carbon atoms of the formula R.sup.a --CH.dbd.CH--R.sup.b, where R.sup.a and R.sup.b are identical or different and each is hydrogen or C.sub.1 -C.sub.15 -alkyl, straight-chain or branched, or R.sup.a and R.sup.b together with the atoms joining them together form a ring system, and from 0 to 10% by weight of ethylene or of a second olefin have the abovementioned meaning as comonomer, characterized by a 230/2.16 MFI from 5 to 1000 g/10 min, a 230/5 MFI from 15 to 3000 g/10 min, n, a molecular weight (M.sub.w) from 75,000 to 350,000 g/mol, a polydispersity (M.sub.w /M.sub.n) from 1.8 to 3.5, a viscosity number from 70 to 300 cm.sup.3 /g, a melting point from 120.degree. to 165.degree. C., an isotactic block length from 25 to 150, and ether extractables less than 2% by weight, based on the total weight of the polymer.
