CELLULOSE-P-TOLUENESULFONATES - A VALUABLE INTERMEDIATE IN CELLULOSE CHEMISTRY

Organo-soluble cellulose-p-toluenesulfonates (tosylates) with an insig nificant incorporation of chlorodeoxy functions were prepared by react ing cellulose dissolved in N,N-dimethyl acetamide/LiCl and used as int ermediates in the design of cellulosics with new, unusual molecular st ructures. Thus, the remaining OH groups were acylated and sulfated yie lding products with controlled lipophily and amphiphily which are prom ising polymers for self-organizing systems. The polarity reversal by t osylation was used for C-substitution reactions. The molecular structu res of the products were proved by FTIR, H-1- and C-13-NMR spectroscop y.
