COMPOSTIONS OF POLYPROPYLENE AND POLYAMIDE |
摘要 |
The invention relates to thermoplastic compositions in which (A) an isotactic polypropylene, optionally containing comonomer, with a melting point of at least 110° C. and (B) a polyamide, (A) and (B) constituting at least 70 wt %, are blended with (C) at least 2 wt % of a grafted functionalized propylene-based elastomer having isotactic crystallinity and containing at least 0.25 wt % of MAH-derived units based on the total weight of (C). Optionally (D) an ungrafted polyolefin may be added with a melting point of less than 100° C., (C) and (D) combined being at least 8 wt % and the wt % of (A), (B), (C) and (D) being calculated on the basis of the total polymer weight of the thermoplastic composition. |
