Mechanical analysis of polymer glasses — •Jörg Hachenberg, Peter Rösner, and Konrad Samwer — I. Physikalisches Institut, Universität Göttingen, Friedrich-Hund-Platz 1, 37077 Göttingen

The mechanical behaviour of polymers close to the glass-transition-temperature is of great industrial interest but still not fully understood on molecular scale. In this work, mechanical spectroscopy and creep recovery measurements are performed highlighting the material properties at low frequencies / long times and the response to dynamic or static loads. PMMA has been chosen as a model system and shows interesting anelastic and Non-Newtonian viscoelastic features. This work is supported by the DFG, GRK 782
