Abstract
The present invention relates to substituted cellulose acetates and methods of use thereof. One embodiment of the present invention provides a composition having a substituted cellulose acetate having a polar substituent that has an oxygen atom covalently bonded to a nonmetal selected from the group of sulfur, phosphorus, and boron; where the nonmetal is present in at least about 0.01% by weight of the substituted cellulose acetate.
Claims26
A composition comprising:
- a substituted cellulose acetate comprising a polar substituent that comprises an oxygen atom covalently bonded to a nonmetal selected from the group consisting of:
- sulfur, phosphorus, and boron;
- wherein the nonmetal is present in at least about 0.01% by weight of the substituted cellulose acetate.
A composition comprising:
- a substituted cellulose acetate comprising a polar substituent selected from the group consisting of:
- a sulfate, a phosphate, a borate, a carbonate, and any combination thereof;
- wherein the polar substituent is present in at least about 0.03% by weight of the substituted cellulose acetate.
A method comprising:
- providing an adhesive comprising a substituted cellulose acetate comprising a polar substituent that comprises an oxygen atom covalently bonded to a nonmetal selected from the group consisting of:
- sulfur, phosphorus, boron, and chlorine;
- wherein the nonmetal is present in at least about 0.01% by weight of the substituted cellulose acetate;
- and
- applying the adhesive on a surface.
