Abstract

PURPOSE: Fibers of aromatic monovinyl polymer are treated with formaldehyde in the presence of an acid catalyst in a solvent as formaldehyde is constantly being fed to produce the titled fibers inexpensively, which is used as an adsorption material because of their high adsorptivity comparable to active carbon and chemical stability.
CONSTITUTION: Fibers of straight-chain aromatic monovinyl polymer such as polystyrene are treated with a solution consisting of an acid catalyst such as conc. sulfuric acid, a solvent for aromatic monovinyl compound such as nitrobenzene and formaldehyde wherein formaldehyde is constantly fed and the reaction is conducted, preferably at 0W30°C, thus producing the objective fibers having aromatic monovinyl polymer chains as the major structure units and 0.3W3mol, per mole of the aromatic ring in the polymer, of oxymethylene groups introduced into the aromatic ring.
