Some aspects of zwitter ion polymerization in the processes of formation of interpenetrating polymer networks based on diisocyanates

Abstract In model conditions with polymerization of methylthiirane on exposure to a tertiary amine in presence of phenylisocyanate additions the authors study the kinetic patterns of the second stage of the process of formation of semi-interpenetrating polymer networks based on the diisocyanates and polar monomers. Assumptions are advanced on the complex nature of the reaction centre responsible for the development of phases I and II of formation of the interpenetrating networks.
