Samples of poly(vinylidene fluoride) (PVF 2 ) and (vinylidene fluoride-tetra fluoroethylene) (VF 2 -VF 4 ) copolymer were etched with a chromium-based etching reagent. The etching rate was lower for the VF 2 -VF 4 copolymer samples than for the PVF 2 samples. The melting point and enthalpy of fusion
## Abstract A new model based on disorder phenomenon concerning the symmetry is proposed for the crystalline structure of form II of poly(vinylidene fluoride) (PVDF). The disorder has the effect that the crystal possesses no unique space group but it consists alternately of monoclinic regions with
