Synthesis and Characteristics of Polyurethane Modified with Polyorganosiloxae
α,ω-hydroxybutyl poly(dimethylsiloxane) prepolymer (HBPS) was prepared from the equilibrium polymerization hydoxyburyl terminated tetramethylsiloxane at 60℃ for 48hrs. Polyurethane modified with polyorganosiloxane (UMPS) was prepared from the reaction of diisocyanate group terminated polyurethane prepolymer and HBPS. The structures and thermal properties of D3, HBPS and UMPS were characterized by FT-IR, NMR spectrum, DSC and TGA analysis respectively.
