POLYMER SOLUTION FOR (METH)ACRYLIC ADHESIVE AND METHOD FOR PRODUCING THE SAME, (METH)ACRYLIC ADHESIVE AND (METH)ACRYLIC ADHESIVE TAPE

摘要

PROBLEM TO BE SOLVED: To provide a polymer solution for (meth)acrylic adhesive excellent in adhesive characteristics and capable of saving a solvent (amount used) and a method for producing the polymer solution and to provide a (meth)acrylic adhesive and a (meth)acrylic adhesive tape. SOLUTION: The polymer solution for (meth)acrylic adhesive comprises a (meth)acrylic polymer and an organic solvent and has 300,000-500,000 weight average molecular weight of the (meth)acrylic polymer, and inertial radius of a (meth)acrylic polymer measured according to a multi-angle light scattering method by using the polymer solution for (meth)acrylic adhesive is≤25 nm.
