INFRARED ANALYSIS OF THE POLYMERIZATION AND LONG-TERM STABILITY OF EPOXY RESINS

Abstract

Infrared analysis of epoxy resins utilizes the known fingerprint for these polymers at 2.95, 10.93 and 11.6 microns bands. Five epoxy compounds were studied and the polymerization monitored during 18 months storage time. Three systems reached a stable condition in less than two months, and two systems were still unstable after 18 months storage time. These data correlate extremely well with electrical resistivity data obtained for three of the systems studied. Both electrical resistivity data and infrared analysis provide a sensitive means of determining the long-term stability of epoxy resin systems.
