EPOXY RESIN ADDUCTS AND THERMOSETS THEREOF

摘要

An epoxy resin adduct comprising the reaction product of an epoxy resin comprising a diglycidyl ether of Formula 1 as defined herein, and at least one reactive compound having two or more active hydrogen atoms per molecule, wherein the active hydrogen atoms are reactive with epoxide groups are described. The diglycidyl ether contains a cycloaliphatic ring of 3-5 carbon atoms. Curable compositions, methods of curing, cured compositions, and articles comprising the epoxy resin adducts are also disclosed. The epoxy resin adduct has improved cure behavior and provides cured compositions having increased glass transition temperature, good weatherability, and a low total chlorine content.

1. An epoxy resin adduct comprising the reaction product of:
an epoxy resin comprising a diglycidyl ether of Formula 1 wherein n is 1, 2, or 3; each R1 is independently hydrogen, C1-12 alkyl, C3-12 cycloalkyl, or C6-24 aryl; and each R3 is independently hydrogen, C1-12 alkyl, C3-12 cycloalkyl, C6-24 aryl, or a glycidyl ether group, with the proviso that the diglycidyl ether has two glycidyl ether groups; and at least one reactive compound having two or more active hydrogen atoms per molecule, wherein the active hydrogen atoms are reactive with epoxide groups.
