Fill-in-the-blank: In the suspension polymerization of PVC, the pH value of the solution has a significant impact on the size of the resin particles. Either too high or too low a pH value can cause the particles to ( ). Buffers are added to the polymerization system to maintain the pH value within a certain range, thereby ensuring the stability of the dispersant and the polymerization system and resulting in PVC resin with an optimal particle size. Answer: Thicker, neutral
In the production of PVC by suspension polymerization, the pH value of the solution has a significant impact on the size of the resin particles. Either too high or too low a pH value can cause the particles to become larger. By adding buffers to the polymerization system, the pH value can be maintained within a neutral range, thereby ensuring the stability of both the dispersant and the polymerization system and resulting in PVC resin with an optimal particle size.

thicken； Neutral. In the production of PVC by suspension polymerization, the pH value of the solution has a significant impact on the size of the resin particles. Either too high or too low a pH value can cause the particles to become larger. By adding buffers to the polymerization system, the pH value can be maintained within a neutral range, thereby ensuring the stability of both the dispersant and the polymerization system and resulting in PVC resin with a favorable particle size.
Thicker-----6.0-9.0-------------------------------
It will cause the particles to become coarser; a buffer is added to the polymerization system to maintain the pH level in the (neutral) range
