Chlorinated poly(vinylidene fluoride) (PVF 2 ) was prepared by introducing chlorine gas into a CCI 4 suspension of PVF 2 at reflux temperature. Polymer crystallinity and softening point decrease, while solubility and adhesion increase with the degree of chlorination. In contrast to PVF 2 , the chlorinated polymer is soluble in low‐boiling common organic solvents, such as acetone, methyl ethyl ketone, and 1,2‐dimethoxyethane. Chlorinated PVF 2 is resistant to dehydrochlorination and is thermally more stable than PVF, chlorinated PVF, PVC, or chlorinated PVC. Chlorinated PVF 2 coatings on wood, prepared by solution casting at room temperature, show outstanding weathering resistance.
