In order to prepare piezoelectric copolymers, vinylidene cyanide has been copolymerized with two styrenes bearing a fluorinated chain in the para position of the aromatic nucleus, The microstructure of the resulting copolymers has been studied by 13 C NMR, with decoupling of fluorine and hydrogen. These copolymers are perfectly altemating and for one copolymer, a partial cristallinity is observed, due to the side fluorinated chain.
