polymers


Im looking for a chemical or solution that will dissolve cured polymers faster than acetone

Paint strippers (methylene chloride/methanol) worked well for me.

Why not just heat the polymer w/ acetone under pressure?

With out the proper gear = Boom

Heated pressurized solvents are a max safety situation.

This is kind of ridiculous. Not all polymers dissolve in the same solvents. Dissolution of polymer is complicated. I, at least, require more information before I can answer your question.

If you mean polystyrene, then hot acetone or DCM (as mentioned) are pretty decent. THF is nearly ideal (not good!), and takes quite some time to dissolve polystyrene.

Otherwise... Look up "theta solvent" and "good solvent," and you will learn the difference between "ideal" and "good." Then, lookup why all of this matters if you would like to determine the molecular weight.

Methyl ethyl ketone and others, it depends on the polymer really. Epoxides have the best chemical stability.

I think your question is not specific enough. What specific polymer are you interested in?

@Xeon...I echo your boom, with an extra kablammmmm!!!!:D
