| description | Water-based pressure sensitive adhesive compositions are disclosed comprising (a) an acrylic emulsion having a glass transition temperature of less than or equal to 20 DEG C, (b) optionally, a dispersant or a silane-containing compound, and (c) an ethylene or propylene copolymer emulsion. In some embodiments, (a) comprises from 75 to 99 wt% of the compositions, (b), when present, comprises from 0.1 to 5 wt% of the compositions, and (c) comprises from 0.1 to 25 wt% of the composition, each based on the dry weight of the compositions. Methods for preparing water-based pressure sensitive adhesive compositions are also disclosed comprising emulsion polymerizing at least one unsaturated monomer, thereby forming an emulsion polymer having a glass transition temperature of less than or equal to -10 DEG C and blending the emulsion polymer together with a dispersant or silane-containing compound and an ethylene or propylene copolymer emulsion.
