Abstract
A inherently tacky pressure-sensitive adhesive copolymer is formed by copolymerizing at least one alkyl acrylate in the presence of a positive amount up to 50 percent by weight of the monomers of a polar acrylate monomer which, when homopolymerized, have a glass transition temperature less than 50.degree.
