    摘要: A new family of high temperature thermoset resins having high glass transition temperatures and enhanced hygrothermal stability that are synthesized using inexpensive starting materials in essentially a single step process. A trifunctional aromatic, wherein at least one of the three functional groups comprises a halogen and the balance thereof comprises OH groups and wherein said aromatic has electron withdrawing properties, is polymerized using an excess of a diol.
