Abstract
A single or multi-stage process for providing compatible thermoplastic blends of polyphenylene ether resins and polyamide resins is provided by combining such resins with a compatiblizing amount of an agent having in its molecule both acyl-functionality as well as at least one of the following functional groups: carboxylic acid or acid anhydride, acid amide, imido, carboxylic acid ester, amino or hydroxyl group.
Claims7
A process for providing compatible blends of a polyphenylene ether resin and a polyamide resin, comprising the steps of:
- a) melt-blending a polyphenylene ether resin and a polyamide resin with an effective compatibilizing amount of a compatibilizing compound which contains in its molecule both
- (i) at least one group having the formula ##STR7## wherein X is F, Cl, Br, I, OR, or ##STR8## wherein R is H or an alkyl or aryl radical;
- and (ii) at least one carboxylic acid, acid anhydride, acid amide, imido, carboxylic acid ester, amino, or hydroxyl group;
- and
- wherein groups (i) and (ii) are covalently bonded through an aryl linkage, and are not simultaneously a COOH group;
- and
- b) neutralizing the blend.
