FTIR and WAXS analyses showed that DEOA had a disrupting effect on the bidentate hydrogen bonding within the hard domains of the polymer. DMS revealed that DEOA softens the foam above the Tg of the soft segment but only causes minor changes in the degree of microphase separation. Annealing treatments were shown to remove the DEOA influence on the microphase separation as well as some of the softening effect. FTIR was used to show that bidentate hydrogen bonding is enhanced through the annealing of DEOA foams. © 2000 John Wiley & Sons, Inc.
