Abstract
Embodiments of the invention provide a reinforced polypropylene comprising a multi-modal molecular weight distribution elastomer and a block composite.
Claims3
A composition comprising:
- polypropylene;
- an elastomer having a multi-mode molecular weight distribution;
- a block composite;
- and,
- optionally, a filler,
- wherein the elastomer having a multi-mode molecular weight distribution has a high molecular weight fraction and a low molecular weight fraction,
- wherein the low molecular weight fraction has a weight average molecular weight ranging from 5 kg/mol to 50 kg/mol,
- wherein the elastomer having a multi-mode molecular weight distribution comprises an I10/I2 of from 18 to 36 and an overall Mw/Mn ratio of from 7.04 to less than 13.81, and wherein the difference of the I10/I2and the overall Mw/Mn ratio is from 10.96 to 22.19.
