PHOSPHORUS-CONTAINING EPOXY RESIN, FLAME-RETARDANT AND HIGHLY HEAT-RETARDANT EPOXY RESIN COMPOSITION USING THE RESIN, AND LAMINATE

摘要

PROBLEM TO BE SOLVED: To provide a phosphorus-containing epoxy resin capable of providing a cured product having excellent flame retardancy and heat resistance, and useful for a prepreg and a laminate.;SOLUTION: This phosphorus-containing epoxy resin is obtained by reacting an organophosphorus compound with a trifunctional epoxy resin, a bifunctional epoxy resin and optionally a bifunctional phenol compound. The flame-retardant and highly heat-resistant epoxy resin composition contains the phosphorus- containing epoxy resin.;COPYRIGHT: (C)2002,JPO
