Abstract

Nylon 11 (.gamma.-phase) is electrically poled after it is crystallized f commercially available nylon 11 by rapidly crystallizing it from the molten state. The .gamma.-phase nylon 11 so obtained exhibits high piezoelectric properties when poled under different poling conditions at different temperatures. The electrically poled .gamma.-phase nylon 11 is used in a transducer.
