dispersion polymerization PVP can be used as thickener, stabilizer and particle size regulator in polymer emulsion polymerization and suspension polymerization. Generally speaking, PVP with larger molecular weight (K&gt;60) acts as a protective agent to prevent suspension precipitation, prevent the aggregation of larger particle size particles in the emulsion and dispersion solution, and make it stable. Low molecular PVP is more suitable for dispersing agents, especially for dispersing low density substances. Of course, the molecular weight and its distribution must be compatible with the particle size and distribution of the dispersion. PVP and NVP copolymers can be used in styrene homopolymerization and copolymerization, suspension polymerization of vinyl chloride, methacrylate and polyurethane, emulsion polymerization of acrylic ester and vinyl carboxylate, which can play an excellent role in dispersion stability, particle size control,viscosity adjustment and resin performance improvement.
