Is there anyone who makes polyvinyl alcohol?
Thread Content
Is there polyvinyl alcohol with a molecular weight of 2000 and an hydrolysis degree of 80%? Is it easy to control? Which friend has looked into the relevant patents? Corning in Japan and Synthetic Chemicals possess technology in this area. I couldn’t find it.
It’s not very difficult; it’s the data for ordinary products
It’s a quite ordinary product; these days, many people are researching PVA with low or high molecular weights.
In which field is the high dielectric constant of polyvinyl alcohol mainly utilized?
Reply to 1# chenfeiyan3025: Reaching an alcoholysis degree of 80 is not easy; it’s only possible using a batch alcoholysis process. The belt-type alcoholysis method definitely won’t work. Although batch alcoholysis can be used, the output of such equipment is low, and methanol consumption is high.
