Abstract
The present invention discloses a hyperbranched cationic mussel-imitated polymer and a method of preparing the same. The hyperbranched polymer disclosed in the present invention has the excellent mussel-imitated non-selective adhesive property, good biocompatibility and adhesive strength adjustability. The method of the present invention includes the following steps: (A) adding an initiator, a RAFT agent and a first reaction mixture to a vessel containing DMF to form a second reaction mixture; (B) stirring the second reaction mixture until homogenous, and introducing argon to a reaction system to remove oxygen in the reaction system; (C) heating and stirring the second reaction mixture to carry out a reaction; (D) after a product with a desired molecular weight being produced, the reaction system being exposed to air and cooled rapidly in a cold water bath to terminate the reaction; and (E) purifying the product to obtain the hyperbranched cationic mussel-imitated polymer.
