Abstract
A curable epoxy resin composition comprising an epoxy resin and a reactive diluent, at least 60% by weight of the total amount of said reactive diluent consisting of a specific etherified polyepichlohydrin monoglycidyl ether and/or etherified polymethylepichlorohydrin monoglycidyl ether. The above etherified product is prepared by addition-polymerizing 2 to 10 mols of a compound selected from the group consisting of epichlorohydrin and methylepichlorohydrin with a monohydric phenol or alcohol and treating the resulting addition polymer with an alkaline substance.
Claims5
A curable epoxy resin composition comprising an epoxy resin having at least two epoxy groups selected from glycidyl and methylglycidyl in the molecule and a reactive diluent, at least 60% by weight of the total amount of said reactive diluent consisting of a compound expressed by the following formula (I) ##EQU5## wherein R is a member selected from the group consisting of straight-chain alkyl containing 1 to 7 carbon atoms, branched-chain alkyl containing 1 to 7 carbon atoms, alkenyl containing 2 to 7 carbon atoms, cycloalkyl containing 5 to 6 carbon atoms, methyl-substituted cycloalkyl containing 6 to 7 carbon atoms, phenyl cresyl and benzyl R' is a hydrogen atom or methyl, a plurality of R' groups may be the same or different, and n is a positive integer of 1 to 9.
