Pressure sensitive adhesives and adhesive articles

摘要: Normally tacky, pressure sensitive adhesive compositions comprise one or more polymers containing pendant functional groups attached to a polymer backbone and having the formula: ##STR1## in which R 1 is divalent organic radical at least 3 atoms length, X organoacyl cyano, wherein said selected from group consisting of (1) conjugated diolefin comprising about 30 weight percent diene monomers 4 8 carbon 0 70 alkenyl-substituted monoaromatic monomers, (2) olefin ester interpolymers monoolefin monomer up 40 an alkenyl alkenol saturated carboxylic acid, (3) olefinically unsaturated acid polymerized (4) ether units, (5) combinations thereof. Such have improved cohesive strength with little no detriment tack adhesion, these improvements are realized without necessity incorporating crosslinking such as N-methylolamides other agents. Pressure adhesive, water-based emulsions, hot melts solutions articles portion surface thereof coated adhesives also provided.
