Acrylic polymer compositions, acrylic pressure-sensitive adhesion tapes and process for producing the same |
摘要 |
An acrylic pressure sensitive adhesive composition comprising 5 to 75 parts by weight of an adherent polymer (a) comprising (meth)acrylic ester component units as principal structural units and having a weight average molecular weight of 50,000 or more; 5 to 40 parts by weight of a tackifier resin (b) comprising (meth)acrylic ester component units as principal structural units and having a weight average molecular weight of 20,000 or less; and 20 to 90 parts by weight of monomers (c) whose principal component is a (meth)acrylic ester, wherein substantially no solvent is contained is provided. Further, a pressure sensitive adhesive tape having a pressure sensitive adhesive layer superimposed on a support surface is provided by coating the support surface with the above acrylic pressure sensitive adhesive composition, which contain a partial polymerizate, and carrying out a polymerization reaction on the support surface. |
