ABSTRACT:
Heat curable epoxy-styrene compositions exhibiting improved processability, low viscosity, long pot life, and fire retardancy which when cured with a special acid anhydride/onium salt epoxy curing blend in combination with a free-radical catalyst, yield cured products exhibiting improved physical properties, such as increased heat deflection temperature, increased flexural strength and increased flexibility.
