Abstract
The cure of modified epoxy resins was monitored by taking ultrasonic measurements. From the time dependence of acoustic parameters it was possible to elucidate the different stages of curing, the gel point, the dynamic glass transition, and the end of the crosslinking reactions. The chemical composition of the epoxy systems was varied in a systematic manner and its influence on the ultrasonic properties was studied. The results show that ultrasonic methods serve as a useful tool for the characterization of curing reactions and highly crosslinked networks.
