Abstract:
1. A polymeric composition comprising a polyurethane polymer derived from a polyisocyanate compound and a polyactive hydrogen compound, said polyurethane having an effective amount of covalently bound, antimicrobially active ammonium groups pendant to the polyurethane polymer in a terminal position and/or as a side chain along the polyurethane polymer backbone, wherein the antimicrobially active ammonium group is derived from a compound of the formula (I): wherein: m is 1 or 2; p is 1; and q=1 or 2 provided that m+q=3; x is 6 to 20; y is 2-8; z is 2-10; L is O, S, NR each R Q ⊖ is halogen, alkyl sulfate, or carboxylate, sulfonate, sulfate, phosphonate or phosphate; or an alkylaminoacrylate compound of the formula (II): wherein: R R Q Z ⊕ is −N ⊕ (R 4 ) 2 R 3 ,−N ⊕ R 4 (R 3 ) 2 , wherein:
