Abstract

Nematic phase polymerization of diacetylenes proceeded without an induction period. The decay rate of monomers was found to be enhanced in a thin film sample. When an external electric field was applied to the thin film, the rate was accelerated with a threshold value of 2500 V/cm which corresponds to that for a dynamic scattering mode.
