Water Soluble Polysiloxanes with Pendant 1-Oxypyridin-3-yl Groups

Abstract

Polysiloxanes with 1-oxypyridin-3-yl groups bonded to silicon were prepared by base catalyzed hydrolysis-polycondensation of dialkoxy silane monomers. The polymers were characterized by IR, IH- and 13C-NMR spectra. Polymers bearing 1-oxypyridin-3-yl functions were soluble in organic solvents like CH2C12. The solubility in hydrogen bonding solvents, such as H20 and MeOH, increased with increase in molecular weight The distribution coefficient for materials with different molecular weight in a water/CHC13 mixture is reported. Quasi-elastic light scattering data indicate that the Stokes diameter for the polymer with molecular weight 9000 increases in the order H20 < MeOH < CH2C12. Structural ramifications of the solvent effect are suggested.
