Carboxy-functionalized polyphenylene ethers and blends containing them |
摘要 |
Carboxy-functionalized polyphenylene ethers containing structural units with a carboxyalkyl group in the 2-position are prepared by redistribution of a polyphenylene ether with a 2-carboxyalkylphenol such as 2-(3-carboxypropyl)phenol (melilotic acid), or by oxidative coupling of a suitable phenol with such a 2-carboxyalkylphenol. The products form compatibilizing copolymers with polymers containing carboxylic acid-reactive functional groups, such as polyesters, polyamides and epoxy resins.
