An acrylic material having antimicrobial characteristics that inhibit bacterial growth includes an acrylic polymer and an antimicrobial agent incorporated therein. The acrylic polymer is a conventional acrylonitrile compound. The antimicrobial agent is incorporated into the amorphous zones of the molecular structure of the acrylic polymer. When the acrylic material is formed using conventional techniques, the antimicrobial additive is incorporated into the amorphous zones of the molecular structure of the acrylic polymer using a solubilizing agent carrier, thereby incorporating the antimicrobial agent into the acrylic polymer. The antimicrobial additive in the acrylic material, incorporated in the manner above, results in substantive controlled migration from within the acrylic material to the surface of the acrylic material, until a point of equilibrium is reached.

L'invention concerne une matière acrylique qui présente des caractéristiques antimicrobiennes pouvant inhiber la croissance bactérienne. Cette matière inclut un polymère acrylique et un agent antimicrobien. Le polymère acrylique est un composé acrylonitrile ordinaire. L'agent antimicrobien est incorporé dans les zones amorphes de la structure moléculaire du polymère acrylique. Lorsque la matière acrylique est formée au moyen de techniques classiques, l'additif antimicrobien est incorporé dans les zones amorphes de la structure moléculaire du polymère acrylique au moyen d'un support d'agent de solubilisation, ce qui permet d'incorporer l'agent antimicrobien dans le polymère acrylique. L'additif antimicrobien ainsi incorporé dans la matière acrylique donne lieu à une migration régulée significative, de l'intérieur de la matière acrylique à la surface de cette dernière, jusqu'à ce qu'un point d'équilibre soit atteint.
