ABSTRACT:
Hard and strong epoxy resin products of high impact resistance are made from a di-epoxy compound, a smaller than equivalent proportion of a dicarboxylic acid which functions as a chain extender, and a bifunctional liquid elastomer, together with a curing agent active at elevated temperatures. Preferably the quantity of bifunctional liquid elastomer is about 5 to 10% of the amount of the di-epoxy compound.
