A method for the preparation of polyphenylene ether resins having increased hydroxyl content and, particularly, increased non-Mannich hydroxyl content comprises reaction of biphenol with polyphenylene ether resin. Polyphenylene ether resins obtained by such method, as well as the reaction products between such polyphenylene ether resins and hydroxyl-reactive substituents, such as epoxy chlorotriazines, and compositions containing such reaction products and thermoplastic resins not normally compatible with polyphenylene ether resin, such as polyester resin are also disclosed. |
