Abstract:
The invention relates to a polymer-cellulosic fiber composition comprising a polymer, a cellulosic fiber, and a quaternary ammonium alkyl salt wherein the latter imparts antimicrobial properties to the composition and functions as a lubricant during the formation of the composition. The quaternary ammonium alkyl salts may be alkyl carboxylate, alkyl sulfate, alkyl sulphonate, alkyl phosphate, or alkyl phosphite. Certain of the salts are new compositions of matter. The method of extruding and the extrudate are also claimed.
Mold-Inhibiting Method And Composition Comprising Dehydroacetic Acid Or Salt Thereof
Disclosed is a method for inhibiting the growth of mold on building materials by application onto and/or incorporation into the building material of a mold-inhibiting composition comprising dehydroacetic acid or a salt thereof and, optionally, an additional fungicidal agent such as a quaternary ammonium compound. A preferred application of the method is the inhibition of mold growth on plasterboard (drywall).
