中文摘要	amphiphilic supramolecular miktoarm star copolymers linked by ionic bonds with controlled molecular weight and low polydispersity have been successfully synthesized via reversible addition-fragmentation chain transfer (raft) polymerization using an ion-bonded macromolecular raft agent (macro-raft agent). firstly, a new tetrafunctional initiator, dimethyl 4,6-bis(bromomethyl)-isophthalate, was synthesized and used as an initiator for atom transfer radical polymerization (atrp) of styrene to form polystyrene (pst) containing two ester groups at the middle of polymer chain. then, the ester groups were converted into tertiary amino groups and the ion-bonded supramolecular macro-raft agent was obtained through the interaction between the tertiary amino group and 2-dodecylsulfanylthiocarbonylsulfanyl-2-methyl propionic acid (dmp). finally, ion-bonded amphiphilic miktoarm star copolymer, (pst)(2)-poly(n-isopropyl-acrylamide)(2), was prepared by raft polymerization of n-isopropylacrylamide (nipam) in the presence of the supramolecular macro-raft agent. the polymerization kinetics was investigated and the molecular weight and the architecture of the resulting star polymers were characterized by means of h-1-nmr, ftir, and gpc techniques.
