(Received 2 December 1993, revised 30 June 1994) The tyt.q' conformation of poly(vinylidene fluoride) (PVDF) is ~ 0.5-0.7 kcal mol - J monomer- t more stable than the all-truns conformation as calculated by molecular mechanics. For vinylidene fluoride-trifluoroethylene copolymer compositions < ~90mo1% vinylidene fluoride, the all-trans conformation is more stable. For PVDF, crystal packing calculations support the distorted tgt.q' conformation predicted by X-ray crystallography.
