ACRYLIC COPOLYMER FOR PRESSURE-SENSITIVE ADHESIVE COMPOSITION WITH EXCELLENT COMPATIBILITY AND DURABILITY FOR WINDOW FILM AND ACRYLIC PRESSURE-SENSITIVE ADHESIVE COMPOSITION FOR WINDOW FILM USING THE SAME

摘要

PURPOSE: An acrylic copolymer is provided not to have crystallization behavior because of excellent miscibility, to have excellent constructability, and to have little residue after removing, and to have excellent durability after adhesion to glass. CONSTITUTION: An acrylic copolymer for window film adhesion is polymerized by a (meth)acrylic acid ester based monomer including a crosslinkable functional group, has molecular weight(Mw) of 800,000-2,000,000, and has the glass transition temperature of (-50) - (-38)C. The adhesive composition comprises the acrylic copolymer and a UV absorber. The acrylic copolymer is obtained through the polymerization of 90-99.9 weight% of a (meth)acrylic acid ester based monomer having C1-12 alkyl group, and 0.1-10 weight% of a vinyl monomer or an acryl monomer having crosslinkable functional group.
