    摘要: 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.

    摘要: A substituted cellulose ester having a cellulose backbone with an organic ester substituent and an inorganic ester substituent derived from the inorganic ester oxoacid catalyst may be utilized in adhesive compositions and articles produced therewith. Producing a substituted cellulose ester may, in some embodiments, involve providing a cellulose ester mixture that comprises a cellulose ester and a solvent; and hydrolyzing a mixture that comprises the cellulose ester mixture, water, and an inorganic ester oxoacid catalyst so as to yield a substituted cellulose ester having a cellulose backbone with an organic ester substituent and an inorganic ester substituent derived from the inorganic ester oxoacid catalyst.
