    摘要: Hot melt adhesive compositions containing a polystyrene-polyisoprene/polybutadiene-polystyrene block copolymer and its use in the manufacture of disposable absorbent articles. The adhesive comprises a thermoplastic polystyrene-polyisoprene/polybutadiene-polystyrene block copolymer having a styrene content of at least 25 wt % and a diblock percentage of less than 30%, a second thermoplastic block copolymer and a tackifier.

    摘要: A low application temperature rubber-based hot melt adhesive having properties particularly well suited for use in the construction of disposable articles has been invented. The adhesive comprises a styrene block copolymer and a type of wax in an amount effective to produce a viscosity at 120° C. of below about 10,000 centipoises, a cube flow at 130° F. (54° C.) of less than about 300%, a DSC crystallization temperature of less than about 75° C. and a storage modulus of less than about 1.0×107 dynes/cm2 at 10 rads/sec (25° C.).
