Abstract
Hydrolysis of p-nitrophenyl acetate catalyzed by cyclodextrin (CD) covalently bound to poly(vinylamine) was carried out. The mechanism of the catalytic process was compared with that of the analog mixture of nonbonded CD and poly(vinylamine). The covalently bonded catalyst exhibits a Michaelis-Menten type kinetics involving an intermediate complex as βCD alone does. NH 2 functions of the polymer act cooperatively with CD residues by a nucleophilic attack of the included substrate. Experiments carried out with polymers of variable degree of substitution by CD showed that the best catalytic power is observed for the systems having the largest excess of amino groups.
