摘要
Crystalline propylene polymers having P.I. values lower than or equal to 3.7, and having, at an MFR (Melt Flow Rate) ranging from 600 to 1000 g/10 min., an Mw value from 100,000 to 60,000, and at a MFR ranging from 1000 to 2000 g/10 min., an Mz value higher than or equal to 140,000, are obtained by way of polymerization with specific supported catalysts.
