Hello Ms. Ilakiya

You can try with Acetonitrile at the temperature around 60°C. Hope it works.

Are you sure it was dissolved? It is also possible to depolymerise PMMA at above Tc = 198 deg.C

Dear Elakkiya,

Regarding your question, I believe that is needed more information about the utilization and dimensions of PMMA mould.

In the paper that you have cited, PMMA was used like a polymer/matrix or as binder to obtain filled compositions with 5-10% pigments, whereas the compression molding and some metallic moulds (I assume) have been used to produce items with different forms.

Function of the thickness and surface are that is needed by you, the solvent casting process can be, more or less effective, and generally will not lead to a performant final product, while a lot of time it will be used for finding the best experimental procedure.

If really you need a mould of PMMA, for more facility I will not exclude the possibility to obtain this mould by mechanically processing from semi-finished parts/rods of PMMA (they are commercially available in a large diameter range, from few mm to 100 mm or more).

Good luck in the finding of the best option and best regards,

Marius

There are many solvent for PMMA ie Toluene,Methyl choride,Chloroform etc.PMMA is our product,produce by Suspension polymerization.To make as a mould you have to cast in sheet and joint with solvent.

Thanks a lot for all the researchers who shared their view in dissolving PMMA. I will work out some of the above method and let you which is working out the best.
