Abstract
Abstract This application discloses an epoxy resin composition containing, as a reactive diluent, 2-chloro-1-chloromethylethyl2,3-epoxy propyl ether. These compositions do not reduce the physical properties of the cured resins as found in cured epoxy resin systems containing the usual diluents such as butyl glycidyl ether.
