PROCESS FOR PREPARING ELECTROSTRICTIVE POLYMERS AND RESULTING POLYMERS AND ARTICLES

摘要

Random copolymers including vinylidene fluoride and hexafluoropropylene that exhibit a large electrostrictive response when subjected to an electric field, articles including such polymers, and methods of preparing the polymers and articles. Electrostrictive responses greater than about 4 percent are obtainable at electric field strengths of 50 megavolts per meter.
