Propylene impact copolymers with balanced impact strength and stiffness |
| abstract |
Disclosed is a propylene impact copolymer comprising a first polypropylene having an MFR 1 within the range from 15 to 40 dg/min; a second polypropylene having an MFR 2 within the range from 50 to 190 dg/min; an elastomeric polymer; and wherein the propylene impact copolymer has an MFR ICP within the range from 6 to 18 dg/min; a 1% Secant Flexural Modulus of greater than 150 kpsi (1030 MPa); and an Izod Impact at 25° C. of greater than 10 ft-lbs/in (530 J/m). The impact copolymer may be produced in a two or three tandem-reactor system wherein the catalyst composition used in the second reactor to produce the second polypropylene is different from the catalyst composition used in the first reactor to produce the first polypropylene. |
