Synthesis and Radical Polymerization of 1,1,2,2-Tetracyanocyclopropylstyrene

Abstract

An isomeric mixture (m-/p: 70/30, mole/mole) of 1,1,2,2- tetracyanocyclopropylstyrene 2 was prepared by cyclopropane formation from bromonalononitrile and vinyl benzaldehyde. The substituted styrene compound 2 was polymerized with free radical initiator to obtain the polymers with multicyano functions in the pendant group. The resulting polymers were soluble in acetone and dimethyl sulfoxide (DMSO) and the inherent viscosities were in the range of 0.27-0.32 dL/g. Solution-cast films were clear and brittle,showing T9g) value of 112 C. Keywords: Piezoelectric properties; Dipole moment; Amorphous materials.
