PP-I-14THE INVESTIGATION OF REACTIONS AROMATIC ISOCYANATESWITH OPEN-CHAIN ANALOGUES OF CROWN ETHERSDavletbaeva I.М., Gumerov А.М., Ahmetshina A.I.Kazan State Technological University, 420015, K. Marks Str., 68davletbaeva09@mail.ruIn last decade there are vast investigations in polymer science directed toproducing of polymer materials with special properties. One of the approaches tocreate such kind of materials based on including of molecular objects which are ableto donor-acceptor interaction into their structure.The interest to investigation of characteristics of molecular organization ofpolymers based on open-chain analogues of crown ethers and aromatic isocyanatesis caused by the possibility of getting polymers with predictable electro-physicalcharacteristics.The purpose of this work is investigation of reaction conditions stimulating to O-polyisocyanate groups formation and stabilization and the influence of intermolecularinteractions at photoluminescent activity and electro-physical characteristics ofpolymers.As an assumption during modeling it was accepted that polymerization ratedoesn’t depend on polymer chain length. Model parameters: initiation,polymerization, cyclization and urethane groups’ formation rate constants. Kineticequations describe time-changing concentration of components.It was established that cyclization and polymerization rate constants ratio can beaccepted as a possibility criterion of opening of isocyanate groups on N=C- or C=Opart. Polymerization rate constant corresponds to polyconnection caused by carbonylopening of isocyanate groups.Supramolecular structures formatting in the presence of terminal О-polyisocyanate chain can have an effect on spectral domain of photoluminescenceand reducing of bulk electrical resistivity.245
