The dispersant with a 72% of hydrolysis level primarily serves as a dispersant agent in the polymerization reaction of PVC, acting as the main dispersant in suspension polymerization. On the other hand, the dispersant with an 80% of hydrolysis level is typically formulated separately in suspension polymerization and serves as the secondary dispersant. Its main functions are to protect the resin and enhance the oil absorption rate of the resin.
