Effect of a reactive diluent on the curing and dynamomechanical properties of an epoxy-diamine system

Differential scanning calorimetry was used to study the influence of an epoxy reactive diluent, vinylcyclohexane dioxide, on the curing reaction of a polymeric system composed of diglycidyl ether of bisphenol A (n=0) and 1,2-diaminecyclohexane (DCH). Heat evolution and glass transition temperature, were measured in terms of the added diluent percentage. Experimental results show that both the curing degree and the glass transition temperature of the polymeric system decrease with an increase in the diluent percentage.
Dynamic mechanical analysis of several samples also showed that T g decreases with the increase of diluent percentage, thus corroborating DSC measurements.
