PURPOSE: An acrylic pressure-sensitive adhesive is provided to ensure excellent initial and final adhesive forces, strippability and stress, and to ensure application to various adherent included at one side or both sides of a substrate. CONSTITUTION: A method for preparing an acrylic pressure-sensitive adhesive comprises: a first step for stirring a mixture consisting of 80-90 parts by weight of alkyl(meth)acrylic acid ester with C2-14 alkyl groups, 1-5 parts by weight of crosslinkable group-containing monomer, 1-5 parts by weight of methyl(meth)acrylate monomer, 5-10 parts by weight of vinyl acetate monomer, and a solvent, and purging the mixture with inert gas; injecting a polymerization initiator three times while purging the mixture with inert gas; and injecting additives to control viscosity. |
