摘要：

The viscosimetric behaviour of diluted DMF solutions of some sulfobetaine polyurethanes and also the influence of some mono- and bivalent metal salts were studied. The studY showed that polyurethane zwitterionomers behave as polyelectrolytes. Films of these polymers complexed with bivalent metals can form, in situ, particles of metal sulfides by exposure to slow H2S flow. Preliminary results show an increased conductivity of films treated with H2S, suggesting a microphase segregation structure.
