Complexation between Poly(methacrylic acid) and Cationically Modified Polyacrylamide
Abstract:
The complexation between poly(methacrylic acid)(PMAA) and cationically modified polyacrylamide(QCPAM) was investigated by fluorescence anisotropy measurements, fluorescence probe studies and fluorescence quenching techniques. It has been demonstrated that the complexation occurs between pH 2 and 8, and the best conditions for complexation are pH 4 and complex ratio 1:1(PMAA:QCPAM, in monomer unit). In addition, along with the complexation, the conformation of PMAA changed dramatically. The pH and complexation dependences of the conformation of PMAA may find some uses in design and synthesis of “intelligent” polyelectrolyte gels.
