摘要: Use of isotactic polypropylene homopolymers or copolymers in processes in which the polypropylene solidifies from a melt, wherein for enhanced speed of solidification of the polypropylene the polypropylene has a melt temperature and a crystallisation temperature not more than 50° C. less than the melt temperature resulting from the polypropylene having been produced using a metallocene catalyst component having the general formula: R″(CpR1R2R3)(Cp′Rn′)MQ2. Cp and Cp′ are a substituted cyclopentadienyl ring, and a sybstituted or unsubstituted fluorenyl ring, respectively. R″ is a structural bridge; R1 is a substituent on the cyclopentadienyl ring distal to the bridge. The distal substituent comprises a bulky group of the formula XR*a; X is chosen from Group IVA. M is a Group IVB transition metal or vanadium and each Q is hydrocarbyl having 1 to 20 carbon atoms or is a halogen.
