| Abstract: | A series of poly(siloxane urethane) block copolymers were prepared by co condensation polymerization. The properties of these polymers were studied by DTA, TG, FT IR, TEM, contact angle and mechanical properties. These materials exhibit microphase separation of the hard and soft segments, however, the outside of siloxane group and the inside of polyurethane group in coating promot the adhesion, hardness, curing velocity and hydrophobicity of polymer coating. |
