Abstract
The conformational equilibrium of 1,2-dichloroethane (DCE) in syndiotactic polystyrene (sPS)/DCE gels has been investigated by using Fourier transform infrared spectroscopy. Results show that the fraction of DCE in the trans conformation (X-T) increases with increasing polymer concentration. From th ese X-T values, by assuming that the crystalline phase in the gel presents the clathrate structure, the amount of DCE included in the crystalline phas e and the fraction of polymer included in the crystalline phase were evalua ted as a function of the gel composition.
