What solvents dissolve PMMA?
Mike VM
solvents (IPA, methanol, acetone, etc.) dissolve (or don't dissolve)
PMMA?
For a more general question: What is the best resource on the Web for
finding out what solvents attack a given material?
Thanks,
Mike VM

about 120000 mw. Dichlorobenzene is used for high mw used in e beam resists,
although there are other non-chlorinated solvents that work for high mw. Let
me check a few references/products and get back to you.

I think Methyl ethyl ketone (2-butanone) will do.
Pure ethanol and pure water do not, but mixtures do.

Ullmann is always my first choice. Then there are some free databases
listing compatibility of polymers with common solvents, these
might also help. And, of course the Polymer Handbook.
You could also try to use (Hansen) solubility parameters, but this
is a bit more complicated.

out there - some made for increased solubility in different solvents.
Lucite International has a resin booklet for Elvacite acrylic resins that
details this.

Lots of more common solvents dissolve PMMA. Copolymers are even more
soluble. Lucite International has an Elvacite acrylic resin pamphlet which
details.

chloroform "was" a good solvent. When i was a kid i used to take a lil
lump of plexiglas (R) and dissolved it in CHCl3 until it was a higher
viscosity liquid. This is what i used as glue to save money while
building the model airplanes and boats (Revell or so). Nowadays
chloroform seems to be a bit more poisonous than it was 25 years ago,
but if you know what you're doing, chloroform is perfect for
dissolving the pmma.

Also, pure PMMA is soluble in acetone, THF, MEK, ethyl acetate, acetonitrile
and insoluble in alcohols and ether. Several other solvents like toluene
give cloudy solutions.

The solvents that dissolve PMMA are dimethylformamide (DMF) and Diethyl carbonate (DEC). DEC work even much better with that.
the non-solvents of PMMA are propylene carbonate (PC), ethylene carbonate (EC) and gamma buterolactone (GBL). They are not the all but the most, according to my on calculations which agree with Hansen solubility theory.
I hope this helps you in somewhat. and should you have any further inquiry I am happy to give a hand.
Good luck

I want to make some coatings apply on gravure machine.
I want know the best solvent to get minimum viscosity with maximum solids.
