ABSTRACT:
A pressure-sensitive adhesive comprises the reaction product of (A) at least one alkyl acrylate liquid polymer containing both terminal and random hydroxyl functionality, and (B) at least one prepolymer of a polyester glycol or a polyalkylene ether glycol with an excess amount of an aromatic diisocyanate. The adhesive has a full range of desirable adhesive properties, including excellent rolling ball tack, 180.degree. peel adhesion and shear adhesion. The adhesive is useful in both solvent and solvent-free systems.
