Industry Share: Preparation of a parent modified acrylate copolymer adhesive 2

Preparation of amphiphilic oligomers 13g octadecyl alcohol, 4g maleic anhydride, and 35g toluene were mixed evenly and poured into a round-bottom flask; Octadecyl maleate was obtained by reaction at 90℃ for 13h. 5g octadecyl maleate monoester, 6.5g polyethylene glycol 600, 0.2g p-toluene sulfonic acid, and 50g toluene was poured into a round-bottom flask, mixed evenly, and reacted at 80℃ reflux temperature for 22h to obtain amphiphilic oligomers.

acrylate copolymer adhesive preparation (1) take 7g ethyl methacrylate, 14g methyl acrylate, 75g xylene, and 25g ethanol mixed evenly; Then, 15g of bisphenol A vinyl alcohol methyl diacrylate and 2g potassium persulfate were added in the stirring state, and the reaction was stirred at 75℃ for 4h. (2) Add 15g of the amphiphilic oligomer, 0.5g glycol dimethacrylate, and 1g ammonium persulfate, stir and react at 75℃ for 5h; (3) Add 0.4g ethylenediamine tetrahydrate, 0.2g citric acid, 1.5g phosphate PM1500, 10g silicon dioxide, and stir until evenly dispersed; (4) In stirring state, vacuum, parental oligomer block modified acrylate copolymer adhesive.
