Molecular Engineering in the Development of Materials for Thermoplastic Recording

A number of internally plasticized copolymers and terpolymers have been prepared which are shown to be suitable for thermoplastic recording. These materials were responsive to both in-air and in-vacuum recording techniques, where the electrostatic charge is applied by corona charging or electron beams, respectively. Several of these materials were tailored for Schlieren optical readout while others possessed properties suggesting their use in recording systems requiring electron beam readout.
