Abstract: A rosin dispersion is a reaction product of, by dry weight based on total dry weight of the rosin dispersion, from 80% to 98% a rosin resin, and from 2% to 20% a dispersant. The rosin resin is processed by at least one method of a) modification, b) hydrogenation or disproportionation, and c) polymerization or esterification from raw material rosins. The dispersant is selected from C18-C32 aliphatic carboxylic acids, olefin (meth) acrylic acid copolymers, and other acid/anhydride modified polymers. A continuous process for preparing the rosin dispersion and an adhesive formulation comprising the rosin dispersion are also included.

Abstract: 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.
