HYPERBRANCHED CATIONIC MUSSEL-IMITATED POLYMER AND METHOD OF PREPARING THE SAME
20200071433 · 2020-03-05 ·

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 comprises 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.

SURFACE TREATMENT LIQUID AND HYDROPHILIC TREATMENT METHOD

An object is to provide a surface treatment liquid which can firmly bond, while coating the surface of a treatment target with an extremely thin film, a coating whose hydrophilicity is unlikely to be lowered even when the coating is brought into contact with fats and the like to the surface of the treatment target and a surface treatment method using the surface treatment liquid described above. In a surface treatment liquid containing a resin (A) and a solvent (S), as the resin (A), a resin is used which includes a constituent unit (a1) that includes an organic group including a quaternary ammonium cation group and having a sulfonic acid anion group at a terminal and that is derived from an N-substituted (meth) acrylamide, and includes a reactive silyl group in at least one of molecular chain terminals, the concentration of the resin (A) in the surface treatment liquid is less than 2 mass % and the pH of the surface treatment liquid is 4 or less.
