Patent Images
1. A thermoplastic composition comprising:
- 100 parts by weight of a resinous composition comprising;
(A) 5-95% by weight of a polyphenylene ether functionalized with a compound containing in its molecular structure at least a double or triple carbon-carbon bond and at least a carboxylic acid, anhydride, amide, imide, ester, amino, or hydroxyl group;
(B) 95-5% by weight of a polyamide; and
(C) 1-100 parts by weight, for 100 parts by weight of mixture A+B, of an olefinic elastomer containing, grafted thereon, a vinylaromatic monomer,wherein the olefinic elastomer is an ethylene/propylene/non-conjugated diene terpolymer, wherein the diene content is approximately from 2 to 20% by weight calculated on the terpolymer, said terpolymer having a Mooney viscosity, ML-4, at 100°
C. ranging from 30 to 90, and an iodine number greater than 5,wherein the vinylaromatic polymer, formed during the graft polymerization of the vinylaromatic monomer, molecular weight (Mw) ranges from about 600,000 to about 1,700,000,wherein the vinylaromatic monomer content is greater than 1% by weight calculated on the grafted polymer, andwherein the vinylaromatic polymer is partially grafted on the rubber-like substrate and partially forms a polymer in physical admixture with the grafter polymer.
