ABSTRACT:
Polyglutaraldehyde (PGL) is polymerized in aqueous base or in aqueous highly polar solvent basic media to prepare powders, castable films or coatings for substrates such as amine substituted microbeads. PGL microspheres can be prepared by suspension polymerization in presence of a surfactant or by precipitating PGL from solution containing surfactant. Magnetic PGL microspheres are formed by suspension polymerization in the presence of magnetic particles such as iron oxide. Polyglutaraldehyde can be converted to a fluorescent polymer by reaction with m-aminophenol or other reagent. Proteins can be readily covalently bound to the polyglutaraldehyde.
