ABSTRACT:
Concentrates of various classical biocides in a polyester carrier resin when incorporated into a substrate resin, preferably a polyolefin such as polypropylene or polyethylene, provide the substrate polymer which biocidal activity with superior resistance to discoloration (yellowing) than when the biocide is directly incorporated into the substrate polymer as a powder at the same total concentration.
