ABSTRACT
Since the pioneering work of P. Castan in Switzerland, the independent pioneering and creative work of S. O. Greenlee in the United States, and the early observations on the reactions of a variety of active-hydrogen compounds with diepoxides by P. Schlack in Germany, the rate of publication of new technical and patent literature on epoxy resins in unparalleled in the thermosetting-resin field. This has been particularly the case with literature on epoxy-curing agents.
