Patent ID: 7173099

Claim:
A propylene homopolymer satisfying: (1) a 25Â° C. hexane soluble content (H25) of 0â€“80 wt %; (2) neither a melting temperature (Tm) nor a melting endotherm (Î”H) measurable by differential scanning calorimetry (DSC); (3 a mesopentad fraction (mmmm) of 30â€“60 mol %: (4) a racemic pentad fraction (rrrr) satisfying the following relationship: {rrrr/(1âˆ’mmmm)}â‰¦0.1; (5) a fraction (W25) eluted at a temperature up to 25Â° C. by temperature programmed chromatography, of from 20â€“100 wt %; and (6) a pentad fraction (rmrm) of more than 2.5 mol %.
