in the reported experiments, alkali-chitin was prepared by a simple procedure which includes a freezing process in a sodium hydroxide-sodium dodecylsulfate system. its alkylations were achieved with various alkyl halides of different chain lengths and bulkiness. the affinity toward water or formic acid was remarkably enhanced by the alkylations in spite of the low degree of substitution. the increase in hydrophilicity was considered to be result from the partial destruction of crystalline structure in the chitin molecule. 16 refs
