【Abstract】 A series of modified polyurethane with different amino siloxane content were synthesized without　the presence of organic solvent .The properties of the materials were investigated using stress-strain analysis, heat- resistance analysis and surface water contact angle analysis, and the microcosmic morphology of the materials were studied by SEM. The results show that the modified polyurethane materials had excellent mechanical properties, heat-resistance, surface hydrophobic properties, and the microphase segregation phenomenon appeares evidently in the materials.更多还原
