Four denture base polymers were studied by using a torsional pendulum apparatus. Shear modulus and mechanical loss tangent were determined after five seconds over the temperature range 20C to 105C, and hence a transition temperature (T G ) was obtained. A polycarbonate had a high TG together with superior elastic properties.
