Patent ID: 8748539

Claim:
A process to make a composition in sequential polymerization whereby a matrix phase is polymerized in one step(s) and then a dispersed phase is polymerized in another step(s), and wherein either the matrix phase or the dispersed phase is polymerized in the presence of the other component; the composition consisting essentially of: (a) a matrix phase which comprises from 60 to 95 weight % of the composition, the matrix phase comprising a polypropylene polymer containing from 0 to 6 mole % of units derived from one or more alpha-olefins other than propylene, and (b) a dispersed phase which comprises from 5 to 40 weight % of the composition, the dispersed phase comprising a copolymer derived from a first comonomer consisting of ethylene, and a second comonomer consisting of a C 4 -C 12 alpha-olefin; wherein the composition has a beta/alpha ratio less than or equal to 1.0 and is cracked to an MFR greater than 35 g/10 min, and wherein a fabricated article made from such composition has a haze value less than about 30% on a 20 mil plaque as measured in accordance with ASTM D 1003.
