    摘要： This invention provides a pressure-sensitive adhesive composition that exhibits excellent pressure-sensitive adhesive properties after crosslinking treatment, does not cause lifting or lifting upon heat treatment or treatment under high-humidity conditions particularly even in the case of a pressure-sensitive adhesive layer having a reduced layer thickness, and has excellent durability. A pressure-sensitive adhesive layer formed using the pressure-sensitive adhesive composition, and a process for producing the same are also provided. Further, an optical member with pressure-sensitive adhesive comprising the pressure-sensitive adhesive layer and an image display using the same are provided. The pressure-sensitive adhesive composition is characterized by comprising 100 parts by weight of an (meth)acrylic polymer and 0.02 to 2 parts by weight of a peroxide, and 0.02 to 2 parts by weight of an isocyanate crosslinking agent, the (meth)acrylic polymer comprising as monomer units 50 to 98% by weight of an (meth)acrylic monomer represented by general formula CH2═C(R1)COOR2, wherein R1 represents hydrogen or a methyl group and R2 represents an alkyl group having 2 to 14 carbon atoms, and 0.1 to 35% by weight of a nitrogen-containing monomer.

    摘要： Polymers whose surfaces are modified by endgroups that include amphipathic surface-modifying moieties. An amphipathic endgroup of a polymer molecule is an endgroup that contains at least two moieties of significantly differing composition, such that the amphipathic endgroup spontaneously rearranges its positioning in a polymer body to position the moiety on the surface of the body, depending upon the composition of the medium with which the body is in contact, when that re-positioning causes a reduction in interfacial energy. An example of an amphipathic surface-modifying endgroup is one that has both a hydrophobic moiety and a hydrophilic moiety in a single endgroup. For instance, a hydrophilic poly(ethylene oxide) terminated with a hydrophilic hydroxyl group is not surface active in air when the surface-modifying endgroup is bonded to a more hydrophobic base polymer. If the hydroxyl group on the oligomeric poly(ethylene oxide) is replaced by a hydrophobic methoxy ether terminus, the poly(ethylene oxide) becomes surface active in air, and allows the poly(ethylene oxide) groups to crystallize in the air-facing surface. In this example, immersion in water destroys the crystallinity as the poly(ethylene oxide) sorbs water and the hydrophobic methoxy group retreats below the surface of the polymer. Also disclosed are methods and articles of manufacture that make use of these polymers.
