A series of polystyrene/poly(ethyl acrylate‐ n ‐butyl acrylate) [PS/P(EA‐ n BA)] latex interpenetrating polymer networks (LIPNs) were synthesized by the two‐stage emulsion polymerization method. The influence of composition, crosslinker content, chain transfer agent, polar group, and feeding sequence on the damping properties of the LIPNs were investigated with a Rheovibron Viscoelastometer. The results show that the PS/P(EA‐ n BA) LIPNs are a partially miscible system, and that LIPNs favor the broadening of the damping temperature range. The influence of crosslinker content of network I on the damping properties of the LIPNs is not the same as that of network II. The damping properties of the PS/P(EA‐ n BA) LIPN is superior to that of P(EA‐ n BA)/PS LIPN. Moreover, the introduction of polar groups into the system can increase the damping properties, and adding chain transfer agent can broaden the damping temperature range. © 1995 John Wiley & Sons, Inc.
