摘要：

The synthesis of polysulfone-polydimethylsiloxane (PSU-PDMS) linear block copolymers has been carried out in solution by condensation of chloro-terminated bisphenol A, diphenylsulfone and alpha, omega-di (hydrogensilyl)-polydimethylsiloxane with Si-C bond. H-1-NMR spectra of the block copolymers allow the estimation of siloxane and polysulfone ratio. The molecular weight of the polysulfone and polysiloxane oligomers and the block copolymers was determined by GPC. Thermogravimetric analysis indicates a thermal stability of block copolymers up to 400 degrees C and allows estimation of the process activation energy. Microphase separation of the block copolymers was observed by differential scanning calorimetry (DSC).
