Abstract

The invention relates to an amphiphilic fluorinated acrylate penta-block copolymer and a preparation method thereof. The technical characteristics are that a name is amphiphilic fluorinated acrylate penta-block copolymer, namely poly-fluorinated acrylate-b-polymethacrylate-b-polyethylene glycol-b-polymethacrylate-b-poly-fluorinated acrylate. A synthetic method uses a bromine-terminated polyethylene glycol as a macro-molecule initiator and uses a one-pan way to gradually charge, that is performs an atom transfer radical polymerization reaction of the macro-molecule initiator with methacrylate, and after the reaction ends, directly adds the fluorinated acrylate to obtain the amphiphilic fluorinated acrylate penta-block copolymer through the atom transfer radical polymerization reaction. The copolymer and the preparation method have advantages of mild reaction condition, simple operation, reduced steps, high product yield, reduced cost, clear product structure and narrow molecular weight distribution, can save time and raw materials, and has potential application in fields of LCD, aerospace coating, photoconductive material, nano-carbon material, pharmaceutical carriers, etc.

Description

technical field

[0001] The invention belongs to the field of polymer synthesis, and in particular relates to an amphiphilic fluorine-containing acrylate pentablock copolymer and a preparation method thereof. Background technique

[0002] Fluoropolymers are a class of functional polymers with excellent dielectric properties, high hydrophobicity, high thermo-oxygen stability, excellent optical properties and chemical stability. However, fluorine materials are expensive and have poor processability. Polyethylene glycol and methacrylate are relatively cheap, among which polyethylene glycol has good biocompatibility and hydrophilicity, and methacrylate and fluorine-containing acrylate have good hydrophobicity. Designing an effective synthesis method to synthesize a copolymer containing these monomers, and adjusting its structural parameters to meet the requirements of different functions, formability and price has become an effective way to solve the current problems of fluoropo...
