Abstract

The segmented polyurethane, Estane is a polyester-urethane (poly(butylene adipate)-poly(4,4′diphenylmethane diisocyanate-1,4 butanediol. In the present paper, conventional contact angle experiments have been performed and the surface energies of the Estane sample as a function of film thickness have been determined. In addition, thermal analysis has been used to measure the calorimetric glass transition (T_g) for this segmented elastomer. Moynihan's area matching method was used to determine the limiting fictive temperature.
