Damping property of polyurethanelpoly(methylmethacrylate-butylmethacrylate-2-Hydroxyeth yl methacrylate) Interpenetrating polymer networks

摘要：

　　Polyurethane/poly(methylacrylate-butylmethacrylate-2-Hydroxyethylmethacrylate) Interpenetrating polymernetworks (IPNs) were prepared by sequential polymerization.Their glass transition performance was measured by using differential scanning calorimetry (DSC).DSC results revealed there are three glass transition temperatures (Tg) for both IPNs samples.Their damping properties were evaluated according to ASTM E756-05.Their loss factor (tan δ>0.3) from 10-1300Hz displays a wide temperature range of 94℃.
