CA 2601738

Compositions comprising a polyvinyl alcohol in combination with a biocide which is a plasticiser, such as a quaternary ammonium compound, or in combination with a biocide and a compatible plasticiser, and wherein the biocide forms a complex with the polyvinyl alcohol, said combination having been heated to above its melting point, said composition having a surface which remains biostatic or biocidal for at least 7 days. A hot melt of the composition may be cast or applied as a film or coating or may be extruded moulded or otherwise into articles. Volatiles formed during heating may be removed from the combination e.g. by low pressure.

La présente invention a pour objet des préparations comprenant un alcool polyvinylique combiné à un agent biocide jouant le rôle de plastifiant, tel qu'un composé d'ammonium quaternaire, ou combiné à un agent biocide et un plastifiant compatible, ledit agent biocide formant un complexe avec l'alcool polyvinylique, ladite combinaison ayant été chauffée au-delà de son point de fusion, et présentant une surface qui conserve ses propriétés biostatiques ou biocides pendant au moins 7 jours. La composition fondue peut être coulée ou appliquée sous forme d'un film ou d'un revêtement, et peut être moulée par extrusion ou par une autre méthode pour former des objets. Les substances volatiles formées au cours du chauffage peuvent être éliminées de ladite combinaison de substances, par exemple sous pression réduite.
