Abstract

p-(2,2,3-Tricyano-3-carbomethoxycyclopropyl)phenoxyethyl acrylate ( 5a) and p-(2,2,3-tricyano-3-carbomethoxycyclopropyl)phynoxyethyl methacrylate ( 5b) were prepared by the reactions of bromomalononitrile with methyl p-(2-acryloyloxyethoxy)benzylidene-cyanoacetate ( 4a) and methyl p-(2-methacryloyloxyethoxy)benzylidenecyanoacetate ( 4b), respectively. Monomers 5a and 5b were polymerized with free-radical initiators to obtain the polymers with multicyanocyclopropane functionalities in the pendant group. The resulting polymers 6a and 6b were soluble in acetone and the inherent viscosities were in the range of 0.20–0.25 dL/g. Solution-cast films showed T<subscript> g</subscript> values in the range of 130–150°C and piezoelectric coeffcients (d<subscript>31</subscript>) of the poled films were 1.5–1.6 pC/N, which are acceptable for piezoelectric device applications.
