    摘要： Pressure-sensitive adhesive tape which has both high adhesion and high cohesion values and adheres strongly to automotive paints and to rubber or plastic foam layers, thus showing great promise for adhering plastic molding strips to the sides of automobiles. The adhesive layer of the novel tape may be made by photopolymerizing (1) acrylic acid ester of non-tertiary alcohol, the alkyl groups of which have an average of 4-14 carbon atoms and (2) N-vinyl-2-pyrrolidone in an amount within 15-50 parts by weight of the total monomers (1) and (2), preferably 25-35 parts.

    摘要： Disclosed is a novel, multi-stage irradiation process for the production of acrylic-based compositions such as adhesives or pressure-sensitive adhesive tapes. The first irradiation step or stage employs electromagnetic radiation at a relatively low average intensity (i.e., 0.1 to 20 mW/cm2) to effect a relatively low extent of monomer conversion, and the subsequent step employs electromagnetic radiation at a relatively higher average intensity (i.e., greater than 20 mW/cm2) to complete the photopolymerization. Also disclosed are acrylic-based psa tape materials made by the novel process.
