    摘要： 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° 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° C. and blending the emulsion polymer together with a dispersant or silane-containing compound and an ethylene or propylene copolymer emulsion. Water-based pressure sensitive adhesives and pressure sensitive adhesive films are also disclosed.
