In this work the PET-PA 66 copolymers are obtained. The characterization of chemical structure of copolymer chain by NMR method is also given. It is shown that
The dependence of measured viscosity on NaCl concentration (0.1 to 3.0M), pH (range of 2—13) and cadoxen composition w<sub>cad</sub> (from 2% to 100%) for the lacque
