| titleOfInvention | Production of polyphenylene ether modified with carbonyl group |
| abstract | PURPOSE: To obtain the subject polyphenylene ether containing an arbitrary number of carbonyl groups in the molecule to improve the compatibility of the polymer by reacting a polyphenylene ether having a specific bond in the substituent with a mercaptocarbonyl compound. n CONSTITUTION: The objective modified polyphenylene ether can be produced by reacting (A) 1mol of a polyphenylene ether having carbon-carbon unsaturated bond on a substituent and obtained e.g. by the oxidative polymerization of 2-allylphenol, 2-allyl-6-methylphenol, etc., with (B) preferably 2-10 mol of a compound of formula (m and n are 1-4; R 1 is 2-6 valent 1-20C saturated aliphatic hydrocarbon group, aromatic hydrocarbon group, etc.; R 2 is alkali metal-oxy, H, OH, aryl, etc.) in an aromatic hydrocarbon solvent (e.g. benzene) in the presence of an organic peroxide (e.g. dibenzoyl peroxide), etc., preferably at 50-150°C. n COPYRIGHT: (C)1992,JPO&Japio |
