Abstract
Two tin‐containing homopolymers, one liquid crystalline and the other non‐mesomorphic, were synthesized and characterized by different relaxation methods (dielectric, calorimetric, NMR). The results prove the existence of two glass transition temperatures related to the dynamics of the main chain and of the liquid crystalline side group, respectively. The reason for this effect is based on a phase separation on nanometer scale.
