Abstract
A poly(phenylene ether)-poly(hydroxy ether)-poly(phenylene ether) (PPE-PHE-PPE) triblock copolymer is formed by reaction of a monohydroxy-terminated poly(phenylene ether) with a diepoxy-terminated poly(hydroxy ether) in the presence of a base. The PPE-PHE-PPE triblock copolymer is useful as a compatibilizer in blends of polar polymers and non-polar polymers. The PPE-PHE-PPE triblock copolymer is also useful as a compatibilizer for non-polar polymers and polar fillers.
