Abstract
A method of forming shaped articles from ionically cross-linked polymer compositions by subjecting an unshaped mass of said polymer composition to radio frequency energy of sufficient degree and time to cause dissociation of the ionically cross-linked regions while maintaining the mass at a temperature below the polymer degradation temperature and subjecting the polymer mass to sufficient shaping forces to form the polymer mass into desired shape.
