Description	Six polyurethane networks were synthesized from Boltorn hyperbranched polyester of the second pseudo generation, α,ω-dihydroxy-(ethylene oxide-poly(dimethylsiloxane)-ethylene oxide) (EO-PDMS-EO) and 4,4-methylenediphenyl diisocyanate. The effect of the EO-PDMS-EO content on the properties of prepared polyurethanes was investigated by dynamic mechanical thermal analysis (DMTA), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), swelling measurements, water contact angle and water absorption. Different techniques (FTIR peak deconvolution, DMTA and SEM) revealed that decrease of EO-PDMS-EO content promotes microphase separation in the synthesized polyurethanes. The results obtained in this work indicate that the synthesis of polyurethanes based on hyperbranched polyester and EO-PDMS-EO leads to the creation of networks with good thermal, thermomechanical and surface properties.
