Abstract
As a result of measuring the spin-lattice relaxation rates of13C nuclei of polyethylene glycol in different solvents in the presence of cellulose acetates, it was found that polyethylene glycol forms H complexes with cellulose acetate in nonaqueous solvents, and the probability of binding increases with a decrease in the molecular weight of the polyethylene glycol. The formation of H complexes results in an effect of inversion of the mobility of the polyethylene glycol molecules of different weights in concentrated solutions of a mixture of polymers. The value of the effect is determined by the donor-acceptor properties of the solvent and the degree of substitution of hydroxyl groups by acetate groups.
