Abstract
The complexation between poly(methacrylic acid) (PMAA) and poly( N, N-diethylacrylamide) (PDEAM) in aqueous phase was studied by UV–vis and fluorescence probe techniques. It was demonstrated that the complexation of PMAA with PDEAM occurs within a pH range of 1–6.5 and along with the complexation, the conformation of PMAA changed from a hypercoiled to a loose coiled form. The complex ratio between the two polymers is 1:1 (PMAA:PDEAM, in monomer unit). Salt effect studies showed that the complexation occurred due to formation of hydrogen bonds between the two polymers. Based upon these conclusions and the “compact micelle-like structure” for PMAA at low pH, a “ladder” model was proposed for the structure of PMAA–PDEAM complex formed at low pH.
