Abstract
A protective membrane and an adhesive composition are provided. The adhesive composition includes an acrylic block copolymer, a crosslinker, and a catalyst. Relative to 100 parts by weight of acrylic block copolymer, an amount of the crosslinker ranges from 1 part by weight to 10 parts by weight and an amount of the catalyst ranges from 0.001 parts by weight to 0.05 parts by weight. The acrylic block copolymer is synthesized from a methacrylic monomer, an acrylic monomer, and a hydroxyl monomer through free radical two-stage polymerization. A glass transition temperature of a homopolymer formed from the methacrylic monomer is higher than a glass transition temperature of a homopolymer formed from the acrylic monomer. The acrylic block copolymer contains an A block segment and a B block segment.
