PROCESS FOR PRODUCING POLYPHENYLENE ETHERS |
摘要 |
Polyphenylene ethers are produced by oxidative polymerization of phenols in the presence of a catalyst comprising the combination of divalent manganese salts, an oxine or derivatives thereof, an alkanolamine, and an alkaline compound. This catalyst has an increased polymerization activity and achieves a higher productivity. In addition, the catalyst enables the polymerization to conduct at relatively high temperatures. |
