✦ Synopsis

Structural investigations were carried out on new cellulose derivatives prepared by heterogeneous and homogeneous reactions. X-ray examination of heterogeneously prepared crystalline cellulose triesters and a triurethane provided new insights into the packing of chains in cellulose microfibrils and in these products. The results were compared with those given by the corresponding homogeneously prepared derivatives. The side-chain conformations for various triesters deviate to some extent from the all-trans arrangement of the bonds of the ester groups.
