Abstract :
New siloxane–sulfone -(AB)n- type segmented copolymers, containing unsaturated units and ester groups in the main chain, were obtained by polycondensation reactions of chloro-terminated arylidene–sulfone macromers and the sodium salt of 1,3-bis(sebacomethyl)tetramethyldisiloxane. The structures of the obtained polymers were confirmed using IR and 1H-NMR spectroscopy and the products were characterized by optical microscopy, thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), gel permeation chromatography (GPC), solubility tests and viscosity measurements. The polymers had T10 values around 300°C, were soluble in aprotic dipolar solvents and showed phase separation in the melt.
