摘要
Four polymeric amphiphiles and biohybrids were produced by free-radical additions of w-functional mercaptans onto a I,2-polybutadiene with a number-average of 40 repeat units. Flocculation or precipitation of polymer was recognized by a steep increase of turbidity and scattering intensity. The results show that the polymer redispersed upon addition of 0.1 N NaOH. The scattering intensity was the same as at the beginning of the titration cycle, indicating that the process was fully reversible. Small-angle X-ray scattering (SAXS) indicated the presence of vesicles in 5 wt % solutions of 1-3. Because of the similarity to liposomes, the biohybrid systems in particular could readily be used as model membranes to study biological recognition processes or for biomedical applications.
