Реферат: ABSTRACT OF THE DISCLOSURE This invention relates to pressure sensitive adhesive formulations which include a saturated midblock thermoplastic elastomer such as a block copolymer of poly-styrene and hydrogenated polydiene such as Kraton? G and a fully saturated tackifying resin derived from petroleum feedstock polymerized in the presence of aluminum chloride and having a ?n ranging from 400 to 800, a softening point of 40 to 70°C and a glass transition temperature less than 45°C whereby the adhesive formulations have a rolling ball tack of less than 10 cm., a 180° peel of from 1 to 4 pounds per inch, a 90° quick stick of from 0.5 to 2.0 pounds per inch and a Polyken probe tack of higher than 400 g/cm2 with a formulation containing 100 to 180 phr of the saturated tackifying resin.
