Polyphenylene ether-polyetheramide blends.

摘要

Blended polymer compositions are described which comprise: (A) at least about 5% by weight of at least one polyphenylene ether; (B) up to about 95% by weight of at least one block polyetheramide; and (C) from 0 to about 3% by weight based upon the total weight of components (A), (B) and any other polymers present in the composition of at least one polyepoxide; with the proviso that when said block polyetheramide has a flex modulus greater than about 75 MPa., said composition contains at least about 0.5% by weight based upon the total weight of components (A), (B) and any other polymers present in the composition of said polyepoxide. The blends give non-delaminating molded parts with good mechanical properties. The blends can be formed from a high-nitrogen polyphenylene ether and a block polyetheramide without the need for using vacuum-vented polyphenylene ether extrudate and without the need for adding a compatibilizer.
