Abstract
Polymer microspheres were synthesized by oxidation polymerization of pyrrole (Py) with functional poly(vinyl alcohol) having pendant Py groups as an emulsifier in water. Polypyrrole (PPy) microspheres had a very narrow particle size distribution ( D W / D n = 1.02 ). Structural ordering of these microspheres was investigated through small-angle X-ray scattering measurements in N-vinylpyrrolidone (VP) monomer. The microspheres formed a lattice with a body-centred cubic structure near the overlap concentration. The polymeric superstructure was constructed by free radical polymerization of the monomer solution.
