A polymer article containing zeolite particles on which metal ion having a bactericidal property, e.g. Ag, Cu or Zn, is provided by an ion exchange reaction shows an excellent bactericidal effect and durability of the effect, but no deterioration of physical properties of the polymer. The polymer article is produced by admixing zeolite particles previously provided with the metal ion with a polymer or by moulding a zeolite-containing polymer into an article and then treating the article with a metal ion solution.

A polymer article having antibacterial properties in which the polymer article comprise at least one polymer and 0.01 to 10% by weight, based on the total weight of the polymer article, of zeolite particles having a specific surface area of at least 150 m2/g, based upon anhydrous zeolite as the stan

A polymer article having antibacterial properties in which the polymer article comprise at least one polymer and 0.01 to 10% by weight, based on the total weight of the polymer article, of zeolite particles having a specific surface area of at least 150 m2/g, based upon anhydrous zeolite as the standard, and an SiO2/Al2O3 mol ratio of at most 14, provided that the zeolite particles retain at least one metal ion having bacteriocidal properties at ion-exchangeable sites of the zeolite in an amount less than 92 percent of the ion exchange capacity of the zeolite.
