Nv. Ptitsyna et al., INTERPLAY BETWEEN THE CATALYTIC ACTIVITY OF A TERMINAL CARBOXYL GROUPAND THE CHAIN-LENGTH OF POLYMERIC CARRIER IN ESTER AMINOLYSIS, Vysokomolekularnye soedinenia. Seria A, 40(9), 1998, pp. 1522-1525
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.
