A cationic star polymer is disclosed of the general formula (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.
本发明揭示了一种阳离子星形聚合物,其一般式为(1):其中w'是大于或等于3的正数,I'是与w'个独立的外周线性阳离子聚合物链P'共价连接的树状聚酯核心。每个链P'包含一个阳离子重复单元,包括:i)选择自脂肪族碳酸酯、脂肪族酯、脂肪族氨基甲酸酯、脂肪族脲、脂肪族硫代氨基甲酸酯、脂肪族二硫代碳酸酯和其组合的骨架功能基;以及ii)包含季铵基的侧链。季铵基包括一个直接共价连接到i)一个带正电的氮和ii)一个芳香环的二价亚甲基基团。
