Removing polymer from test tubes

Try chlorinated solvents or ketonic ones, such as chloroform, chlorobenzene, methylene chloride, or MEK Mixtures reported to be good for PMMA are isopropanol / MEK 1:1 by weight at temperature above 25°C, or ethanol / carbon tetrachloride. However, if molecular weight is too high, dissolution may be long. Be patient !

Hope this will help Regards

Beat it to the punch. Treat the tube with silane prior to running the reaction.

Actually you do not have to make the polymer in glass since you are making in bulk and do not need to stir. Just find a reaction vessel that it does not stick to. For information purposes you might google what they use for casting PMMA. Frank
