IMPACT-RESISTANT COMPOSITION BASED ON A POLYAMIDE RESIN AND ON A BLEND OF AT LEAST ONE GRAFT COPOLYMER WITH POLYAMIDE BLOCKS AND A LOW-DENSITY ETHYLENE POLYMER |
摘要 |
The invention relates to a composition based on an impact-resistant thermoplastic polyamide resin, comprising as a blend: - from 60 to 98 wt% of polyamide resin (A) and - from 2 to 40 wt% of a blend of at least one graft copolymer with polyamide blocks (B) composed of a polyolefin backbone and at least one polyamide graft in which the grafts are attached to the backbone by the residues of an unsaturated monomer (X) having a functional group capable of reacting with an amine-terminated polyamide, the residues of the unsaturated monomer (X) being attached to the backbone by grafting or copolymerization through its double bond, and a non-reactive ethylene polymer (C) that is miscible with (B) and has a density below 0.960 g/cm<SUP>3</SUP>. This composition has improved impact resistance properties and also a satisfactory fluidity. The invention also relates to the process of obtaining said composition and also to its use for manufacturing products or parts obtained by injection moulding or extrusion. |
