摘要:
Low molecular weight polyphenylene ether (PPE) is made from higher molecular weight PPE without using solvents by extruding the higher molecular weight PPE with a phenolic modifier and a redistribution catalyst. The low molecular weight PPE has a Mw/Mn polydispersity greater than about 2 and a Mn ranging from about 10,000 to about 20,000.
