摘要
The dissolution of polyvinyltetrazoles of various structures in organic solvents was studied by calorimetry. The solubility of these polymers is controlled by competition between their self-association and the donor-acceptor interaction with the solvent. A relationship between the heat of solution and the physicochemical parameters of the solvents was established for poly(2-methyl-5-vinyl)tetrazole. The heats of solution of poly(5-vinyltetrazole)s bearing methyl substituents depend on the procedure of preparation and are governed by the packing density of these polymers.
