Fiber Society Meeting. 1p. Technical Abstract: In order to develop new high volumes uses of cellulose and cotton, a series of reactive benzyl-cellulose and benzyl-cotton derivatives were prepared to investigate their chemical and physical properties. Later we want to blend them with compatible monomers (epoxies and isocyanates) and polymers so composites, films, and membranes with cellulosic polymers and fibers can be prepared for existing and new applications. Towards this goal, we used the method of Daly and Caldwell (Journal of Polymer Science: Polymer Letters Ed., 1979, 17, 55-63) to prepare benzyl cellulose and benzyl cottons, and extended the work to demonstrate nitrobenzylation and reduction with indium in ethanol to afforded amino benzyl derivatives of cellulose and cotton. In addition, we prepared triazole elastomer 5 via [3+2] cycloaddition polymerization of PEO-diazide 3, and diporpargylether of bisphenol-A 4. In this presentation we will discuss the synthesis, characterization, and new use development of these new macromers, polymers, and fibers.
