    摘要: A linear styrene-isoprene-styrene block copolymer composition comprised of linear polymeric blocks wherein the block copolymer composition has a coupling efficiency of 25 to 82 percent, a polystyrene content of from 19 to 27 percent by weight, a polystyrene block molecular weight (peak polystyrene equivalent molecular weight as determined by gel permeation chromatography) of 12,000 to 18,000, and an overall molecular weight (peak polystyrene equivalent molecular weight as determined by gel permeation chromatography) of from 170,000 to 280,000. The invention also contemplates adhesive formulations comprising these block copolymer compositions and a tackifying resin.

    摘要: Pressure-sensitive adhesive tape, having an untensilized crystalline isotactic polypropylene or linear high density polyethylene film backing with a pattern of alternating ridges and valleys on one side, is especially adapted for use as a tab closure for diapers. The ridges are so disposed that, when a tab is cut from the tape, at least some of the ridges extend at an angle of 60.degree. or less to the lateral edge of the tab, thereby minimizing any tendency toward inadvertent tearing.

    摘要: A hot melt coatable pressure-sensitive adhesive is provided showing high levels of adhesion to low surface energy films and nonwovens. The adhesive elastomeric phase comprises from 78 to 98 parts by weight of a diblock A-B type block copolymer with an elastomeric block of 1,3-polybutadiene with 2 to 22 parts by weight of multiblock A-B type block copolymer. The tackifying material comprises 140 parts or less of a solid tackifying resin and a liquid tackifier to provide an adhesive having a composite midblock glass transition temperature of less than -10.degree. C.
