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 (Tg) for this segmented elastomer. Moynihan's area matching method was used to determine the limiting fictive temperature.
