The purpose of this study was to examine the properties and synthesis feasibility of water‐soluble hybrids of poly(vinyl pyrrolidone) (PVP) or a PVP copolymer. PVP was first mixed with different concentrations of tetraethoxysilane (TEOS) to produce PVP/SiO 2 hybrids. Second, PVP/sodium polyacrylate (PAANa) copolymers were prepared and further developed into hybrids and then were analyzed and tested with methods such as Fourier transform infrared, NMR, X‐ray spectroscopy, and scanning electron microscopy. According to the results of the experiments, the PVP polymer or its copolymer generated hydrogen bonding with the OH group in SiO 2 with both PVP/SiO 2 and PVP–PAANa/SiO 2 hybrids. With an adequate concentration of TEOS, the hybrids exhibited increased heat resistance. Moreover, the roughness and holes in the hybrids increased with increasing TEOS concentration. However, when the TEOS concentration exceeded 6%, the roughness began to drop. Finally, all the hybrids were water‐soluble but possessed inferior solubility when used with organic solvents. © 2006 Wiley Periodicals, Inc. J Appl Polym Sci 100: 2164–2170, 2006
