Alternating copolymers of vinylidene cyanide with substituted styrenes (mixtures of meta and para) and with para-substituted styrenes have been synthesized and characterized by means of d.s.c, and g.p.c. The lowest values for T~ have been observed with the copolymers which include both meta- and para-substituted styrenes. The values of permittivities of these copolymers at 30°C are in the range 3-6 and dielectric losses are close to 10-2. Some of these copolymers could have piezoelectric properties.
