Abstract: A hot melt pressure sensitive adhesive comprising a) from about 15% to about 40% by weight of a block copolymer having a coupling efficiency of less than about 75%; b) from about 20% to about 50% by weight of a tackifying resin selected from the group consisting of those tackifying resins having a softening point of less than about 100° C.; c) from about 30% to about 50% by weight of a plasticizing oil; and d) up to about 15% of a compatible polymer wherein the total polymer content does not exceed 40% by weight of the adhesive wherein the hot melt pressure sensitive adhesive fails cohesively during use.

Abstract: A high heat resistant hot melt adhesive composition, its method of manufacture and its use on plastic and metallized foil containers, structures and the like is described herein, which adhesive contains a blend of an amorphous polyalphaolefin polymer, a solid benzoate plasticizer and a hydrocarbon tackifier where the elevated peel value of the resulting adhesive composition is greater than 160.degree.

Abstract: A hot melt pressure sensitive adhesive comprising a) from about 15% to about 30% by weight of a linear styrene-ethylene/butylene-styrene copolymer having a styrene content from about 15% to about 35% by weight and a coupling efficiency of less than about 75%; b) from about 20% to about 50% by weight of a tackifying resin selected from the group consisting of those tackifying resins having a softening point of less than about 100.degree. C.; c) from about 30% to about 50% by weight of a plasticizing oil; and d) up to about 15% of a compatible polymer wherein the total polymer content does not exceed 30% by weight of the adhesive wherein the hot melt pressure sensitive adhesive fails cohesively during use.

Abstract: A method and composition of packaging an adhesive composition, especially a thermoplastic or thermosetting hot melt adhesive. The method comprises the steps of providing one substantially uniform separate portion of the adhesive composition; sufficiently solidifying said portion for packaging; and substantially completely surrounding said sufficiently solidified portion with a biodegradable polymeric packaging material. The packaging material being meltable together with the adhesive composition and blendable into said molten adhesive composition, the kind and amount of said biodegradable packaging material being chosen so as not to disadvantageously affect the properties of the adhesive composition when blended into the molten adhesive and applied to a substrate.
