(673g) Novel Skeleton Intermediates Derived From Bisphenol A Available for Preparing Bola, Gemini or Polymerizable Surfactants

In this paper, novel skeleton intermediates available for preparing bola, gemini or polymerizale surfactants were synthesized by the anionic polymerization of propylene oxide and bisphenol A. The novel Gemini surfactants were prepared by introducing sulfonate group at the benzene ring of the intermediates and the chemical structure of the products was confirmed by FTIR, MS and NMR. CMC and γ_cmc of the Gemini surfactants were studied and it was found that the Gemini surfactants were about one order of magnitude more efficient at forming micelles (CMC) than conventional surfactants. Bola surfactants have been prepared by introducing sulfonate group at the end hydroxyls of polypropylene oxide chain alternative. As we imagined, polymerizable surfactants can also be prepared by introducing polymerizable groups in the end hydroxyls of polypropylene oxide chain. Polymerizable surfactants which contain polymerzable groups are attracting scientific and industrial attention for their application in the fields of soap-free emulsion polymerization, nanomaterials preparation.
