Abstract
A (meth)acrylate-based adhesive polymer composition is improved by the use of itaconic acid and a hydroxyalkyl (meth)acrylate, such as hydroxyethyl acrylate, polymerized therein. From 1 to 5 weight percent itaconic acid and from 1.5 to 17 weight percent hydroxyalkyl (meth)acrylate are used to improve the combinations of tack and shear strength in these adhesive polymers. With an optional tackifier, these polymers are found especially useful in pressure sensitive adhesive applications.
