In-Line Monitoring of Dielectric and Fluorescence Spectroscopy During Polymer/Filler Compounding



Anthony J. Bur, S C. Roth, Y E. Lee, N Noda, M M. McBrearty


A new multi purpose instrument has been used to obtain real-time dielectric and fluorescence spectroscopy from polymer resins compounded with inorganic fillers. The istrument, which is mounted at the exit of an extruder, contains a flow-through slit channel that provides a constant geometry platform for dielectric and fluorescence sensors and olther sensors that can be added as needed. The results of real-time monotoring of nylon 6 and ethyl vinyl acetate copolymer (EVA) compounded with organo modified montmorillonite clays are persented. Real-time dielectric data are corrected for electrode and conductivity effects before analysis yields information about dielectric relaxation phenomena. Significant differences in dielectric dispersion parameters were observed for clay nanocomposites in the aggregate, intercalated, and exfoliated states.
