METHODS FOR BIODEGRADABLE DERIVATIZATION OF CELLULOSIC SURFACES

摘要

A solid cellulose-containing material having a surface and comprising hydroxyl groups on the surface, wherein at least a portion of the oxygen atoms contained in the hydroxyl groups available on the surface are attached directly via an ester bond to a carbon atom of an acyl group of an alkanoic acid derivative having the formula (I) or formula (II):         R-CO-X     Formula (I),         X-CO-R-CO-X₁     Formula (II),wherein R is a straight-chain, branched-chain, or cyclic aliphatic hydrocarbon radical having from 6 to 50 carbon atoms, and wherein X and X₁ are independently Cl, Br, or O(CO)OR, and wherein the surface exhibits a water contact angle of between 60° to about 120°.
