PREPARATION AND SEPARATION OF COMPLEXES PREPARED BY TEMPLATE POLYMERIZATION

Acrylic acid (AA) was polymerized in the presence of poly(vinylpyrrolidone) (PVP) as a template polymer in an aqueous medium. The result was a complex of poly(acrylic acid) (PAA) and PVP. Comparison of the FTIR spectrum of the complex with that prepared by mixing of PAA and PVP indicates that the complex is composed of PAA and PVP. The separation of the complex was achieved by methylation, indicating that the polymers were interacting through hydrogen bonding. The low yield of separation indicates the existence of some grafted complex. When the complex was prepared by using PVP of different molecular weights, the yield of separation changed. The degree of the separation decreased as the molecular weight of PVP increased. © 1990, American Chemical Society. All rights reserved.
