Patent ID: 7112630

Claim:
A water-soluble, antimicrobial active polymer represented by Formula wherein: n and m are the number of repeated units, n is 0.7–0.95 and m is 0.05–0.3 provided that n+m=1; and R 1 is a silane derivative represented by Formula 2: wherein: R 2 is selected from the group consisting of an alkylene of 1–30 carbon atoms, a heteroalkylene of 1–30 carbon atoms, an arylene of 6–20 carbon atoms, an arylalkylene of 6–20 carbon atoms, a heteroarylene of 6–30 carbon atoms, and a heteroarylalkylene of 6–30 carbon atoms, each of which is unsubstituted or substituted with a halogen, a hydroxyl, a nitro, a cyano, an amino, an amidino, a hydrazine, a hydrazone, carboxylic acid or a salt thereof, sulfonic acid or a salt thereof, phosphoric acid or a salt thereof, an alkyl of 1–20 carbon atoms, an alkenyl, an alkynyl, a heteroalkyl of 2–20 carbon atoms, an aryl of 6–20 carbon atoms, an arylalkyl of 6–30 carbon atoms, a heteroaryl of 6–30 carbon atoms, or a heteroarylalkyl of 6–30 carbon atoms; R 3 is selected from the group consisting of an alkylene of 1–12 carbon atoms, an alkenylene or an alkynylene of 1–12 carbon atom, and an heteroalkylene of 1–12 carbon atoms, each of which is unsubstituted or substituted with a halogen, a hydroxyl, a nitro, a cyano, an amino, an amidino, a hydrazine, a hydrazone, carboxylic acid or a salt thereof, sulfonic acid or a salt thereof, phosphoric acid or a salt thereof, an alkyl of 1–20 carbon atoms, an alkenyl, an alkynyl, a heteroalkyl of 2–20 carbon atoms, an aryl of 6–20 carbon atoms, an arylalkyl of 6–30 carbon atoms, a heteroaryl of 6–30 carbon atoms, or a heteroarylalkyl of 6–30 carbon atoms; R 4 and R 5 are independently one of hydrogen, or an alkyl of 1–5 carbon atoms; and R 6 is one of a hydrogen, a hydroxyl, or an alkoxyl of 1–5 carbon atoms.
