Abstract
A new approach to the design of hyperbranched polymers, the cocyclotrimerization of mono-and diisocyanates is proposed. The kinetic scheme for the synthesis of hyperbranched polyisocyanurates was considered and calculated in the generating-function formalism. New theoretical relationships were obtained that make it possible to predict the critical conversion and a change in the structural and molecular-mass characteristics of hyperbranched polyisocyanurates in the course of the reaction, depending on the initial ratio of monoand diisocyanates and on the relative reactivity of isocyanate groups.
