Abstract
Some properties of the product of tetrazolylethyl cellulose ether alkylation are studied. A comparative analysis of a change in the properties of heterochain (tetrazolated cellulose) and carbochain [poly(5-vinyltetrazole)] polymers when ionic N–H unsubstituted tetrazole rings are replaced with N-methyl-substituted ones in their macromolecular structure is performed. It is shown that the structure of the side heterocyclic substituent rather than the nature of the backbone exerts the decisive effect on the behavior of the polymers.
