✦ Synopsis

Abstract

A new hydrogel that combines poly(ethylene glycol) and β‐cyclodextrin has been synthesized. Both components are linked by using a diisocyanate (HDMI), first by end‐capping the poly(ethylene glycol) with isocyanate groups an then reacting it with β‐cyclodextrin, forming urethane links. Hydrogels of molar compositions (β‐cyclodextrin/poly(ethylene glycol)) ranging from 1/4 to 1/14 have been synthesized. These hydrogels swell quickly and their water contents depend upon temperature. The gels are temperature resistant and show an elastomeric behavior. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 102: 1162–1166, 2006

The melting temperature of the gels of the poly(vinyl alcohol) (PVA)/ethylene glycol (EG) system was measured. It was found that the temperature was independent of the thermal hysteresis. The apparent enthalpy of the fusion of the junction, DH, was 206 kJ/mol for a high molecular weight atactic PVA
