Therefore, it can be concluded that the system is fully miscible, which agrees with previous studies using PC/PMMA blends in which molecular. MMAtwo collaborative consortium. The machining process was conducted without using any. 3, Page 6/7 PMMA Resists for T-gate and Other Imaging Processes PMMA is a high resolution positive tone resist for e-beam and X-ray lithographic processes. 1/4 (19) Bundesrepublik Deutschland Deutsches Patent- und Markenamt *DE102005039916A120070308* (10) DE 10 2005 039 916 A1 2007. PMMA is usually synthesized by the radical polymerization of MMA, and the anionic and coordination polymerizations are also available. 1. .
