Abstract: The compatibility and dynamics of latex bidirectional/nterpenetrating polymer networks （LBIPNs） and latex IPN（LIPN） of poly（vinyl acetate）（PVAc） and poly （butyl acrylate ）（PBA） are investigated by means of dynamic mechanical spectroscopy （DMS） and nuclear magnetic resonance （NMR） techniques. The results of DMS show that the compatibility of the LBIPNs is much better than that of the corresponding LIPN and depends to, a large extent on the distribution of PVAc both in the core and in the shell.
