ABSTRACT:
What is disclosed is a method for preparing antimicrobially effective foams using certain silanes as co-catalysts, co-surfactants and antimicrobial agents to give soft, resilient, fine-celled foams that are capable of reducing the number of, or eliminating, microorganisms in all types of media. Such foams themselves are not susceptible to attack by the microorganisms. An example is the use of (CH.sub.3 O).sub.3 Si(CH.sub.2).sub.3 N.sup..sym. (CH.sub.3).sub.2 C.sub.18 H.sub.37 Cl.sup.- in a flexible polyurethane foam formulation to give a fine-celled, soft, resilient foam which is antimicrobially effective over a long period of time.
