Abstract
The kinetics of aminolysis of n-nitrophenyl acetate in the presence of soluble polymeric catalysts based on PEGs containing terminal carboxy l groups was studied. The relationship between the catalytic activity of the terminal group and the chain length of polymeric carrier was es tablished, and the contribution of a carrier to an additional accelera tion of the reaction associated with autosolvation of the prereaction complex was determined.
