Hi folks, I want to spin coat a substrate with 950k PMMA. My problem is that I can bake to no more than 100ºC and this is the reason I can't use the commercial PMMA diluted in chlorobenzene or anysol. I have found that dichloromethane is a good solvent for PMMA and with a low boiling point (40C). The question is if this solvent, the dichloromethane, will cut the chains of the PMMA giving a lower MW PMMA (unwanted) or if it will keep the original lenght of the PMMA?
Thank you very much in advance.
