NEW AMPHIPHILIC POLYMERS - POLY(N-ALKYLACRYLAMIDE-CO-VINYLPYRIDINIUM)

A series of new amphiphilic polymers containing various amounts of N-m ethyl-4-vinylpyridinium units as hydrophilic part and N-dodecylacrylam ide or N-decylacrylamide units as hydrophobic part have been prepared by quaternizing the cognate copolymers. Their behaviour in aqueous sol utions has been studied by viscometry, as well as by fluorescence spec troscopy and tensiometry. Results are discussed in detail and a confor mational model of the macromolecules at the interface (water / methylc yclohexane) is proposed in relation to the formation of microdomains i n the aqueous media.
