Abstract

A polyphenylene ether having at least one functional end group of the formula: ##STR1## in which R is a divalent C_1-12 aliphatic group, n is 0 or 1, and R₅ is hydrogen, a C_1-8 alkyl group or a hydroxy-C_2-8 -alkyl.

Claims

1. A polyphenylene ether having at least one functional end group of the formula:

##STR9## in which R is a divalent C_1-12 aliphatic group, n is 0 or 1.

2. The polyphenylene ether of claim 1, wherein the functionalized polymer product contains from 0.2 to 10 mole % of functional groups based on the monomer units of the polymer product.
