Abstract: AN EPIHALOHTDRIN IS REACTED WITH A MIXTURE OF OF ISOMERIC CYCLODODECANEDIOLS IN THE PRESENCE OF A LEWIS ACID. THE REACTION PRODUCT IS DEHYDROHALOGENATED WITH ALKALI. THE DEHYDROHALOGENATED REACTION PRODUCT, WHEN HARDENED, SUPRISINGLY SHOWS SUPERIOR ARC AND SURFACE LEAKAGE CURRENT STRENGTH AS COMPARE WITH CONVENTIONAL HARDENED EPOXY RESINS. THE MIXTURE IS ISOMERIC CYCLODODECANEDIOLS PREFREABLE HAS A DIOL CONTENT OF 95-100% BY WEIGHT.
