Provided are synthesis methods of polymerizing aniline or derivatives thereof. The production of polyaniline or polyaniline derivatives is controlled by the type of oxidant added in the reaction medium. The methods include the step of using a safe and environmentally friendly carbomethyl cellulose (CMC) or modified CMC as an oxidant in the polymerization reaction to produce polyaniline or aniline derivatives. Synthesis methods of producing O-CMC and O-CMC-S oxidants are also provided herein.

A process for producing a crosslinked cellulose ether including the steps of: (a) contacting at least one cellulose material with at least one alkalization reagent to form an activated cellulose material; (b) contacting the activated cellulose material of step (a) with at least one etherification reagent to form an uncrosslinked cellulose ether; (c) subjecting the cellulose ether of step (b) to a simultaneous or stepwise washing and/or granulating step; (d) adding at least one crosslinking agent to the uncrosslinked cellulose ether during the washing and/or granulating of step (c) to form a crosslinked cellulose ether; and (e) any other optional components desired; and a crosslinked cellulose ether produced by the above process.

Disclosed herein is a polymer composition comprising an effective amount of a hydrophobically-modified polymer having functional groups along the backbone occupied by a fatty anhydride moiety. The polymer composition has a potent hemostatic action by gelling blood upon contact, and is suitable for treating internal and external bleeds. As disclosed herein, the modified polymer can be generated without the use of toxic reagents that would require removal from the product. Further, compositions are shelf stable even in a flowable form. That is, the hydrophobic grafts are not lost under product storage conditions (e.g., room temperature storage).

The present disclosure provides methods of preparing cellulosic superabsorbent polymer (SAP) using cellulose powder.
