Multilayer membranes of DPPC (1,2-dipalmitoyl-sn-glycero-3-phosphatidylcholine) and mixture DPPC/POPC (1-palmitoyl-2-oleoyl-sn-glycero-3-phosphatidylcholine) in excess of water were investigated by small angle X-ray scattering and neutron small angle scattering. Structural parameters of lipid bilayers were determined in a wide temperature range. It was shown that addition of the POPC to the DPPC/H2O does not change the temperature of the DPPC main phase transition T-m. The observed phase separation occurs for the system DPPC/POPC/H2O up to the pre-transition temperature T-r (gel phase - ripple phase) of the DPPC multilayers.
