摘要

@@Aqueous solutions of poly(vinyl methyl ether) (PVME) exhibit bimodal Lower Critical Solution Temperature (LCST) miscibility behavior with moderate critical solution temperatures around 35~37℃.1-3 The phenomenological results from experiments1-10 and theoretical predictions8-10 cannot provide detailed molecular insights into the observed anomalous phase behavior. Previous work in our group7 utilized quantum mechanics calculations to optimize the structures of the PVME model compound interacting with clusters of 2~5 water molecules and the detailed molecular packing structures with relatively lower energies were obtained.
