Comparative study was made of parameters of molecular mobility of two series of “comb-like” polymers; cholesteryl esters of poly-N-methacrylyl-ω-aminocarboxylic acids and of poly-ω-methacrylyloxycarboxylic acids. It was established that the hyd

The dielectric polarization and dipole moments of gels formed by comb-like polymers have been investigated. It is shown that the macroscopic formation of a gel is proceeded by a conformational transition at the intramolecular level in the solution, w
