Polyvinylidene fluoride (PVDF) fibers are used in a variety of applications, including office chairs, fishing equipments, and athletic shoes, due to their excellent chemical resistance and stain resilience. The fiberization process requires careful control of the melt flow rate of the PVDF resin, which in turn requires the average molecular weight of the polymer to be adjusted according to the polymerization conditions. In this study, a series of PVDF resins were prepared by suspension polymerization under different process conditions. The chemical structures of the resulting PVDF samples were then analyzed by nuclear magnetic resonance, gel permeation chromatography, and scanning electron microscopy. In addition, the properties of the PVDF resins, such as melt flow rate, tensile modulus, thermal stability, and melting temperature, were investigated. Finally, the correlation between the polymerization conditions and the physicochemical properties of PVDF was investigated.
