Rheokinetics curing of epoxy oligomers produced by industry with amine hardener
Abstract
The influence of molecular weight, molecular mass distribution, heterogeneity and low-molecular fraction content on the rheokinetics of epoxy resins DER-332, DER-330, ED-20, ED-16 cured with an amine-type hardener triethylenetetraamine was studied. Three characteristic stages of the epoxy oligomers curing were determined. The stages depend on the molecular characteristics of the oligomers.
