Abstract
The invention relates to a pressure sensitive adhesive prepared from an aqueous emulsion polymer. The polymer is prepared by reacting at least one ethylenically unsaturated monomer and from about 0.1 to about 5 weight percent, based on the total weight of ethylenically unsaturated monomer, of a water-soluble or water-dispersible polymerizable surfactant having a terminal allyl amine moiety. The pressure sensitive adhesives may be used in all types of tapes, labels, decals, packaging, electrical insulation, and surgical bandaging.
