Abstract
Novel polyphenylene ether-polyamide compositions having improved compatibility, elongation and impact properties as well as improved processability are prepared comprising a polyphenylene ether, a polyamide and a property improving amount of an acyl modified polyphenylene ether compatibilization agent. These compositions may further comprise alkenyl aromatic polymer or a rubbery polymer.
Claims21
A thermoplastic composition comprising
- (a) a first polyphenylene ether resin;
- (b) a polyamide resin;
- and
- (c) a compatibilization agent which is a second polyphenylene ether modified with an acyl functional compound wherein said acyl functional compound contains in its molecule both (i) at least one group having the formula ##STR15## where X is F, Cl, Br, I, OH, ##STR16## where 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;
- wherein groups (i) and (ii) are covalently bonded through a divalent hydrocarbon radical and are not both simultaneously a COOH group;
- and wherein compound (c) is presentin an amount sufficient to effect compatibilization of resinous components (a) and (b).
