| Abstract: | The modified polysiloxane(M-PDMS)was synthesized by leading the hard segment of isocyanate into polysiloxane(PDMS) chain.Using polyethylene glycol(PEG)and 2,4-TDI of different relative molecular mass to synthesize polyurethane prepolymer(PUP),making interpenetrating network via crosslinking polymerization,the modified polysiloxane/polyurethane elastomer(M-PDMS/PUE) was prepared.The influence of PEG relative molecular mass and M-PDMS/PUP mass ratio on the damping performance and morphology of material was re... |
