Abstract
Polyureas with the dibenzylic system on the macromolecular chain are c onsidered. The behaviour of these polyureas during cyclization with ox alyl chloride, leading to polyparabanic derivatives, was studied. The influences of polymer structures and reaction conditions on the hetero cyclization is discussed. All the polymers were characterized by eleme ntal analyses, inherent viscosities, i.r. spectra and thermogravimetri c analyses.
