PURPOSE: Provided is a biocide-polyester carrier condensate useful for providing biocidal activity onto a polymer substrate without generating decoloration and/or alteration of colors. CONSTITUTION: The condensate comprises (A) 1-75wt.% of biocidal material and (B) 99-25wt.% of polyester carrier resin. A biocidal active polymer composition having decoloration(yellowing)-resistant property is prepared of the polymer substrate and the condensate comprising the components(A) and (B) in an efficient amount. The biocidal material(A) is preferably 2,4,4'-trichloro-2'-hydroxydiphenyl ether and the polyester carrier resin(B) is a homopolyester or copolyester prepared from aliphatic, alicyclic or aromatic dicarboxylic acid or diol, or hydroxycarboxylic acid.
