Abstract
Materials made of polyhydroxylated or polyaminated polymers can be rendered bacteriostatic or fungistatic by treating the materials with a solution of certain N-oxiranemethane N,N,N-trialkylammonium compounds in a base, and either spin drying the treated material and storing it protected from air for at least three hours, or drying the treated material and holding it at a temperature higher than 80.degree.
