Miscibility and Phase Behavior of Poly (Enaminonitrile)/Peo Blends

摘要

Recently, we have been synthesizing and studying the properties ofpoly(enaminonitriles), a novel class of polymers which exhibit the thermal stability of aramides but are readily soluble in simple, volatile solvents such as THF and diglyme, as well as in polar, aprotic solvents. Spectroscopic evidence supports specific hydrogen bonded interactions between the NH-groups of the enaminonitrile unit and the oxygen atoms in the ether. Ether solutions exhibit lower critical solution temperature behavior. For the glymes, the critical
