Flow Microcalorimetry and Competitive Liquid Sorption .1. Sorption Behavior of Some Polymer Networks
Three different polymer networks (polymer resins) are investigated by selective liquid sorption from 1-propanol/water mixtures. Network 1 is a non-polar, non swelling, macroporous resin. Networks 2 and 3 are macroreticular polar (hydrophilic) ion exchangers, which swell in the binary liquid mixture. The enthalpy of displacement isotherms accompanying the sorption processes are determined by flow microcalorimetry. The enthalpy isotherms reveal the differences in polarity of the polymer network.
