| description | Provided is preparation technology for a high-performance solvent copolymerization acrylate pressure-sensitive adhesive. The adhesive comprises the following components, by weight ratio: 65-90% of a soft monomer, 10-30% of a hard monomer, and 3-5% of a crosslinking monomer. The adhesive also comprises a solvent, the weight of which is 10% of the total weight of monomers at an initial reaction stage, is 10-20% of the total weight of monomers at an early stage of a growth stage, is 40-60% of the total weight of monomers at a later stage of the growth stage, and is 138-163% of the total weight of monomers at a final reaction stage, and an initiator, the weight of which is 0.03-0.5% of the total weight of monomers. According to the invention, the copolymerization acrylate is high in average molecular weight and wide in molecular weight distribution. The molecular weight of the copolymerization acrylate can be measured through gel permeation chromatography, and has a weight-average molecular weight in a range of 450-900 kg/mol and a molecular weight distribution index in a range of 4-20. |
