    A new class of copolymers potentially suitable for an imprint process is investigated. They are composed of methyl-methacrylate and a methacrylic acid, where the acid component increases the glass temperature and thus the thermal stability. The results obtained are compared to previous experiments with a methyl/butyl acrylate and the suitability for an imprint process is discussed. A modified processing sequence is proposed, where pressure is applied during the heating phase, resulting in superior imprint quality of, for example, periodic patterns.
