Is the type of dispersant used related to the drying temperature? Using a dispersion system based primarily on polyvinyl alcohol provides good gel retention; the PVC film is relatively dense, and a higher drying temperature is required Is a dispersion system based primarily on hydroxypropyl groups required to use a lower drying temperature? Is there such a saying? What are the differences in the drying temperatures for PVC in the two different dispersion systems?
Personally, I think the impact is minimal, as after the resin is formed, what affects drying mainly depends on recovery and centrifugation.
