HIGH TEMPERATURE EPOXY RESINS

摘要

A multi-functional epoxy resin precursor having the formula (I), in which R1 to R3 inclusive are independently selected from hydrogen, C1 to C3 alkyl or haloalkyl, or halogen; and an epoxy resin derived from this precursor and in particular a multifunctional epoxy resin comprising the dehydrochlorination product of a coupled product of this precursor and a second N-diglycidyl epoxy precursor through its active site para to the meta nitrogen to produce a molecule having functionality greater than four are described.
