This work demonstrates the synthesis of polysiloxane urethane ureas using bismuth(III) neodecanoate, revealing unique phase characteristics.
Polysiloxane–(butylene oxide)–urethane–ureas were synthesized in the presence of bismuth(III) neodecanoate. The resulting polymers were studied by differential scanning calorimetry (DSC), thermomechanical analysis (TMA), optical and atomic force microscopy (AFM); their deformation and strength characteristics were determined. It was found that the polymers obtained are characterized by two glass transition temperatures, indicating the formation of two phases.
