Dielectric properties of poly(enaminonitrile)s

Abstract

Poly(enaminonitrile)s (PEANs), a new class of thermally stable aromatic polymers, possess excellent thermal stability, good mechanical properties and are easily soluble in many organic solvents. Flexible, tough films can be cast from these solutions. These polymers undergo a 'curing' reaction at 300-350 degrees C to insoluble, more dimensionally stable materials without evolution of volatile byproducts. Ne summarize here the dielectric data measured at a frequency of 100 kHz, 25 degrees C for some PEANs, and discuss the results in relation to their structures.
