SYNTHESIS OF DIGLICYDILESTERS WITH ALICYCLIC IMIDE STRUCTURE AND THEIR THERMAL AND TERTIARY AMINE-CATALYZED CURING

The synthesis of new diglycidylester compounds with bicyclo[2.2.2]oct- 7-ene units was carried out from the previously synthesized diimide-di acids and epichlorohydrin in excess using BTMA as catalyst. These comp ounds were characterized by spectroscopic techniques and have been cur ed either thermally or using 4-dimethylaminopyridine as tertiary amine catalyst. The study of curing reaction was carried out through therma l analysis of the reaction by differential scanning calorimetry (DSC). The concentration of the tertiary amine affects the reaction mechanis m of epoxide curing, but it does not influence the thermal properties of the final product. (C) 1995 John Wiley and Sons, Inc.
