Abstract
Hot melt and pressure-sensitive adhesives may comprise highly-plasticized cellulose esters, e.g., a cellulose ester and a plasticizer, the plasticizer included in an amount of about 30% to about 60% by weight of the cellulose ester. A highly-plasticized cellulose ester adhesive that is non-tacky at room temperature may be utilized by heating an adhesive to yield an adhesive melt, the adhesive comprising a cellulose ester and a plasticizer, the plasticizer included in an amount of about 15% to about 60% by weight of the adhesive; applying the adhesive melt to a first surface; and adhering a second surface to the first surface with the adhesive.
