Abstract
PURPOSE: Title adhesive which is non-adhesive in a normal condition but exhibits excellent adhesiveness on heating, comprising a hot melt adhesive consisting of a styrene/butadiene block copolymer and a specific modifying polymer.
CONSTITUTION: To 100pts.wt. of a styrene/butadiene block copolymer is added 10W60pts.wt. of a modifying polymer such as a coumarone resin or a xylene resin, having a cloudiness of at least 30% to a styrene homopolymer, a cloudiness of at least 50% to a butadiene homopolymer and a softening point of 80W160°C to obtain a hot melt adhesive which is non-adhesive in a normal condition but becomes adhesive on heating. The adhesive is applied to a release paper by solution coating or melt extrusion coating to form an adhesive layer. The adhesive layer together with the releae paper is heat-pressed to a material board for forming hard boards. Thus, a material board with an adhesive layer is produced.
