Formed polymeric material having bacteriostatic or fungostatic properties, which is the reaction product of: (a) a precursor polymer having at least two active hydrogen atoms capable of imparting elastomeric properties to the polymeric material; (b) a chelating agent having at least one active hydrogen atom; (c) from 0 to about 0.2% by weight, based on the weight of the reaction mixture, of a metal-containing urethane forming catalyst; and (d) a polyisocyanate in amounts less than the amount stoichiometrically equivalent to the content of active hydrogen atoms of (a) and (b). |
