Abstract
A new in-line process monitoring instrument, a dielectric slit die, was used to examine compounding of polymer/clay nanocomposites. It is a multi-purpose sensing device for measuring polymer dielectric, rheological and optical properties during extrusion. We report the results of compounding nylon 12 and polyethylene ethylvinyl acetate copolymer with organo modified clays. We show that ionic conductivity is a major contributor to the dielectric loss at high processing temperatures. Curve fitting of the dielectric loss as function of frequency allows us to separate loss due to DC conductivity and dielectric dispersion loss.Proceedings Title
