Polymeric compositions that include polyurethane polymers derived from a polyisocyanate compound and a polyactive hydrogen compound. The polyurethane compound is at least partially endcapped with a group including at least one antimicrobial quaternary ammonium compound. The polymeric composition of the present invention is capable of forming a self-supporting film. The polymeric compositions are suitable for coating substrates to effectively kill or prevent the growth of microorganisms such as bacteria, mold, mildew, algae fungi and the like. The polymeric compositions are particularly useful for protecting construction materials used in moist, outdoor environments to prevent discoloration or decay from microorganisms and for surfaces in health care facilities to mitigate the spread of pathogens.
本发明涉及包括由聚异氰酸酯化合物和多活性氢化合物制备的聚氨酯聚合物的聚合物组合物。聚氨酯化合物至少部分末端带有包括至少一种抗菌季铵化合物的基团。本发明的聚合物组合物能够形成自支撑薄膜。聚合物组合物适用于涂覆基材以有效地杀灭或预防细菌、霉菌、霉变、藻类真菌等微生物的生长。聚合物组合物特别适用于保护用于潮湿、户外环境中的建筑材料,以防止微生物引起的变色或腐烂,并用于卫生保健设施中的表面,以减轻病原体的传播。
