Abstract

Abstract The kinetics of n-butanol addition to isocyanate in the presence of organotin compounds and their polymer-supported analogues has been investigated. The functionalized polymer chain creates steric hindrances to the formation of non-reactive complexes which include organotin sites. The catalytic activity increases by a factor of 10– 100 as compared with low molecular weight analogues.
