Embodiment 1
[0021] (1) Preparation of acrylate derivatives
[0022] During preparation, under electromagnetic stirring in an oil bath, 300mL of dichloromethane, 67.9g of tetraethylene glycol and 15.2g of triethylamine were successively added to an absolutely anhydrous three-necked flask, and slowly added dropwise 15.6g of triethylamine under the protection of nitrogen. g methacryloyl chloride, heated to 25°C-40°C, stirred for 24 hours until a light yellow liquid appeared, then transferred the above reaction mixture to a one-necked bottle, and spin-dried to obtain a unilateral esterification product. Next, dissolve the esterification product in anhydrous dichloromethane, pour it into a dried three-neck bottle filled with triethylamine with a syringe, and slowly drop the acid fluoride containing perfluoropolyether chain under the protection of nitrogen. , heated up to -80°C to 25°C, stirred and reacted for several hours to obtain the acrylate derivative used in the present invention.
