Abstract
Functionalized polyphenylene ethers are prepared by mixing with various trialkylammonium maleates or fumarates in the melt, in the absence of free radical initiators. They are useful in the preparation of resinous compositions comprising polyphenylene ethers and polyamides or polyesters. Such resinous compositions preferably also contain impact modifiers.
