Influence of Quaternary Ammonium Salts on Cellulose Modificationreaction in a homogenious media.. However,solutions of native cellulose are extremely viscous, so it is unlikely that substrate concentration levels high enough to allow commercially feasible production of derivatives could be employed.

R. Timman,A. J. Hermans,G. C. Hsiaoessible via a chemical modification route. In other cases it may be desirable to effect a simple chemical modification reaction to prepare a less common or more reactive polymer such as poly(iodomethyl styrene) from a more readily accessible but less reactive precursor such as poly(chloromethyl styrene).
