    摘要: 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.

    摘要: A salt catalyst comprises an ionic complex of i) a nitrogen base comprising one or more guanidine and/or amidine functional groups, and ii) an oxoacid comprising one or more active acid groups, the active acid groups independently comprising a carbonyl group (C═O), sulfoxide group (S═O), and/or a phosphonyl group (P═O) bonded to one or more active hydroxy groups; wherein a ratio of moles of the active hydroxy groups to moles of the guanidine and/or amidine functional groups is greater than 0 and less than 2.0. The salt catalysts are capable of catalyzing ring opening polymerization of cyclic carbonyl compounds.
