ABSTRACT:
A process for dielectrically heating and thermoforming a non-polar thermoplastic material by electromagnetic field energy is accomplished by the addition of a polar domain-containing material having at least one nitrile group to the thermoplastic material. Compositions comprising thermoplastic material and a polar domain containing material useful in this process are also described.
