  • Cationic polymers for antimicrobial applications and delivery of bioactive materials
    Patent number: 8709466
    Abstract: A cationic star polymer is disclosed of the general formula (1): I?P?]w???(1), wherein w? is a positive number greater than or equal to 3, I? is a dendritic polyester core covalently linked to w? independent peripheral linear cationic polymer chains P?. Each of the chains P? comprises a cationic repeat unit comprising i) a backbone functional group selected from the group consisting of aliphatic carbonates, aliphatic esters, aliphatic carbamates, aliphatic ureas, aliphatic thiocarbamates, aliphatic dithiocarbonates, and combinations thereof, and ii) a side chain comprising a quaternary amine group. The quaternary amine group comprises a divalent methylene group directly covalently linked to i) a positive charged nitrogen and ii) an aromatic ring.
