ABSTRACT:
A method of improving epoxy resin compositions to provide a cured resin having improved glass transition temperature and toughness characteristics is provided. The method includes providing in an epoxy resin composition an effective amount of a 9,9-bis(hydroxphenyl)fluorene composition. The fluorene component acts as a chain extension agent and provides for increased glass transition temperature and less cross-link density. As a result, improved toughness occurs. In preferred applications a toughening agent is provided in the resin composition, to further enhance toughness. Preferred resin compositions, cured resins and methods of providing improved cured resins are also provided.
