Abstract: front page image
(EN)A polymer composite comprising a thermoplastic polymer compounded with a phenolic antioxidant, an organo-disulfide antioxidant, and a silver-based antimicrobial agent. The specified combination of antioxidant stabilizers is superior in inhibiting undesirable discoloration of thermoplastic polymers in the presence of compounded silver-based antimicrobial agents. A process of preparing such a composite, comprising compounding the phenolic antioxidant and organo-disulfide antioxidant with the thermoplastic polymer prior to compounding the silver-based antimicrobial agent with the thermoplastic polymer.
(FR)La présente invention concerne un composite polymère comprenant un polymère thermoplastique mélangé avec un antioxydant phénolique, un antioxydant organo-disulfide, et un agent antimicrobien à base d'argent. La combinaison spécifiée des stabilisants antioxydants est supérieure en ce qui concerne l'inhibition d'une décoloration non souhaitable de polymères thermoplastiques en présence d'agents composés antimicrobiens à base d'argent. L'invention concerne également un procédé de préparation d'un tel composite, comprenant le mélange d'un antioxydant phénolique et d'un antioxydant organo-disulfide avec le polymère thermoplastique avant le mélange de l'agent antimicrobien à base d'argent avec le polymère thermoplastique.
