Abstract
Hot melt adhesive compositions suitable for disposable constructions are prepared from tackifying resins, oil diluent and a substantially radial styrene-butadiene block copolymer, the copolymer having a styrene content greater than about 35% by weight, a molulus at 300% elongation of at least 4.5 MPa and a solution viscosity less than about 1000 cps.
