A polyolefin moulding composition essentially comprising a polyolefin derived from an olefin having at least 3 carbon atoms, of the formula R<a>-CH=CH-R<b>, in which R<a> and R<b> are identical or different and are hydrogen or straight-chain or branched C1-C15-alkyl, or R<a> and R<b>, together with the atoms connecting them, form a ring, where the polyolefin moulding composition can contain up to 10% by weight of ethylene or a second olefin as defined above as comonomer, having a molecular weight Mw of > 80,000 g/mol, a polydispersity Mw/Mn of from 1.8 to 3.5, a viscosity index of > 70 cm<3>/g, a melting point of from 130 to 160@C, a directional transparency of > 30% and an ether-extractable content of less than 2% by weight. |
