Pressure-sensitive adhesive composition from a blend of polymers. Groves, James D. (Minnesota Mining and Mfg. Co., USA). Eur. Pat. Appl. EP 457566 A2 21 Nov 1991, 16 pp. DESIGNATED STATES: R: CH, DE, ES, FR, GB, IT, LI, NL, SE. (European Patent Organization). CODEN: EPXXDW.Several reagents with their cas registry numbers 29590-42-9 and 79-06-1 are used here. CLASS: ICM: C09J151-00. ICS: C09J153-00. APPLICATION: EP 91-304354 15 May 1991. PRIORITY: US 90-525155 17 May 1990. DOCUMENT TYPE: Patent CA Section: 39 (Synthetic Elastomers and Natural Rubber) Section cross-reference(s): 38 Title compns. having high peel adhesion to polar and nonpolar surfaces, and high tack and static shear, comprise a blend of a tacky rubber-based pressure-sensitive adhesive and a pressure-sensitive adhesive compn. comprising C1-14-alkyl (meth)acrylate polymer with grafted polymeric moieties having a glass transition temp. (Tg) >20° and a wt.-av. mol. wt. >2000. A tackified and stabilized Kraton 1657 rubber adhesive was blended with acrylamide-acrylic acid-isooctyl acrylate-2-polystyrylethyl methacrylate graft copolymer soln. adhesive in various proportions to give a pressure-sensitive adhesive showing good peel adhesion to glass, Al, polyolefins, and stainless steel. .
