ABSTRACT:
A polyolefin molding composition essentially comprising a polyolefin derived from an olefin having at least 3 carbon atoms, of the formula R.sup.a --CH.dbd.CH--R.sup.b, in which R.sup.a and R.sup.b are identical or different and are 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 connecting them, form a ring, where the polyolefin molding composition may contain up to 10% by weight of ethylene or a second olefin as defined above as comonomer, having a molecular weight M.sub.w of >80,000 g/mol, a polydispersity M.sub.w /M.sub.n of from 1.8 to 3.5, a viscosity of >70 cm.sup.3 /g, a melting point of from 130.degree. to 160.degree. C., an aligned transparency of >30% and an ether-extractable content of less than 2% by weight.
