| Abstract: | Polydimethylsiloxane-b-poly(ethylene oxide)block polymers(DMS-b-OE)were used to improve the compatibility of polydimethylsiloxane/polyurethane(PDMS/PU)blends.It was found that the compatibilization effect of DMS-b-OE was related to the chemical structure of the blended polyurethane.DMS-b-OE can promote the compatibility of the blends of PDMS with poly (tetramethyl oxide)urethane,and the resulted blends have a good mechanical properties. |
