Application of PVP in polymerization reaction:The viscosity and colloidal protection function of PVP make it have important applications in polymerization reactions, especially emulsion polymerization. Adding a small amount of PVP in suspension polymerization can play a role in dispersion stability, thickening and particle size control, such as suspension polymerization of methacrylate and polyamine ester. In the emulsion polymerization system of acrylate and vinyl acetate, appropriate amount of PVP-K60 or PVP and styrene copolymer was added to make the reaction system disperse uniformly and stably, and the viscosity, polymer particle size and particle size distribution could be adjusted by adjusting the molecular weight and dosage of PVP, and some properties of the resin could be improved. When -3%PVPK60 was added to the suspension polymerization of polyaminase, the polymer powder size was uniform, the particle size was between 800-100 microns, and the residual monomer was less than 0.5%.
