ABSTRACT:
A pressure sensitive hot melt adhesive comprising a block copolymer and 60 to 95 parts of a liquid diluent, the adhesive being characterized by a midblock Tg less than -10.degree. C., a G' less than 15.times.10.sup.4 dynes/cm.sup.2 at 10 rad/s, 25.degree. C., a G" of 1 to 6.times.10.sup.4 dynes/cm.sup.2 and a tensile strength greater than 10 psi exhibit superior properties, without the need for any curing operation after cooling.
