    摘要: An acrylic pressure-sensitive adhesive composition which contains a high molecular weight polymer, is excellent in cohesive force and adhesive strength and can be prepared without using an organic solvent. The acrylic pressure-sensitive adhesive composition is produced by a process which comprises radical-polymerizing monomers containing an alkyl (meth)acrylate using carbon dioxide as a diluent to thereby prepare a pressure-sensitive adhesive composition containing an acrylic polymer having a weight average molecular weight of 400,000 or more. The polymerization pressure ranges from, for example, about 5.7 to 40 MPa, AND the polymerization temperature ranges from, for example, about 20 to 100° C.

    摘要: A method and apparatus for producing a foamed pressure-sensitive adhesive tape or sheet having a fine cell structure with a good production efficiency without through complicated steps are provided. The method comprises subjecting a mixture containing monomers of a polymer constituting a foamed pressure-sensitive adhesive layer to polymerization in an inert fluid in a supercritical state or a liquid state under pressure, and ejecting the polymerized composition obtained on a substrate under a pressure lower than the pressure in the polymerization to form a foamed pressure-sensitive adhesive layer applied on the substrate. The apparatus comprises a pressure vessel for polymerizing monomers of a polymer constituting a foamed pressure-sensitive adhesive layer under pressure, an inert fluid supplying means for supplying an inert fluid in a supercritical state or a liquid state to the pressure vessel, and an ejection means for ejecting the polymerized composition obtained by polymerizing the monomers.

    摘要: A method for tackifying the surface of a soft layer, which comprises tackifying the surface of the soft layer by an interfacial contact reaction between the soft layer or a reactive interlayer provided thereon, and a pressure-sensitive adhesive layer. Since sufficient adhesion can be obtained with a reduced thickness of the pressure-sensitive adhesive layer, the merits of the soft layer are not impaired.
