Why is methanol added for washing at the end of the polymer production process?
Thread Content
Does anyone know why methanol is used for washing after the production of certain polymers? If you know, please explain it to me. Thank you! ~~~ This post was last edited by qq375170364 on 2009-3-8 21:19]
I only know that it is used in some experiments to terminate reactions (deactivate the catalyst).
Methanol is an excellent organic solvent that can effectively clean those polymers
Stop the reaction, precipitate the polymer, add washing polymer
For polymers obtained by certain solution polymerization or slurry polymerization, ice methanol is an excellent precipitant that can rapidly separate the polymers from the solution. For polymers synthesized by bulk polymerization, since the final product contains some monomers that have not been completely volatilized, methanol can effectively remove these small molecular monomers.
