Baile, Y. Chou, J. Saam] Summary: Certain diols can undergo polycondensation in aqueous emulsion with either dicarboxylic acids or aliphatic aldehydes to give polyester or polyyacetals. The process occurs under mild conditions and requires water insoluble liquid monomers, the presence of a sulfonate surfactant and mobile cations which can ion exchange at the oil-water interface. An acidic catalyst is not necessary. The degrees of polymerization are modest but they exceed those normally expected of polyesterifcations in such an environment. The driving force is thought to be the heat of condensation of the water produced as vapor in the oil phase. Springer-Verlag, 1990 Baile M.
