Studies of Polyurethanes and Epoxy Curing Reactions.

Abstract

The research performed by the Polymer Science and Engineering Department at the University of Massachusetts (Amherst) during the period 10/15/78 to 10/15/79 is summarized in this report. Several polybutadiene-containing polyurethanes and their hydrogenated derivatives were synthesized and characterized using dynamic mechanical and infrared analyses. The cure mechanism for a particular epoxy resin using dynamic mechanical relaxation techniques was studied in detail. The kinetics of the curing reaction of an epoxy resin composed of diaminodiphenyl sulfone and tetraglycidyl 4,4' diaminodiphenyl methane epoxide was studied using dynamic spring analysis. The curing reaction was found to be first order. Activation energies were determined. (Author, modified-PL).
