摘要：

In order to obtain some silylcellulose derivatives, five types of celluloses with different polymerization degrees (DP =327-1100) were used. The obtained silylcellulose derivatives were characterized from the crystallinity point of view as a function of both the substitution degree and characteristics of the used celluloses in their synthesis. The change of the crystalline structure as the result of silylation reaction was evidenced, the crystallinity of silyl derivatives depending on the substitution degree(DS) and on the nature of substituent used.
