Abstract
We present an investigation to study the degradation of PMMA, poly(methyl methacrylate), and ARP-610, poly(methyl methacrylate-co-methacrylic acid), during e-beam and DUV exposure. The change in the chemical structure of the polymer materials were analyzed using UV, IR, NMR spectroscopy, gel permeation chromatography and GC-MS. The formation of anhydrides within the isotactic parts of the co-polymer causes a bimodel and multimodal distribution of the fragments and, therefore, a more efficient dissolution process.
