摘要

Using a two-stage emulsion polymerization method, a series of poly(methylmethacrylate-acrylonitrile)/poly(ethyl acrylate-n-butyl acrylate) [P(MMA-AN)/P(EA-nBA)] latex interpenetrating polymer networks(LIPNs) were synthesized by varying AN content, ratio of network Ietwork II, crosslinker content, and introducint chain transfer agent. The damping properties of the LIPNs were investigated using a Rheovibron Viscoelastometer. The results indicates that a suitable content of AN can improve the damping properties of the LIPNs. Three kinds of fillers were incorporated into the LPINs, respectively, to measure the change in the damping properties. Mica and TiO_2 both increased the damping properties of the LIPNs over the wide temperature range. For TiO_2-filled LIPNs, it was observed that the tan #sigma# values exceeded 0.4 over 112.6degC temperature range from -50 to 72.6degC.
