Investigation of High Temperature Isobutylene Polymerizations Utilizing Real-Time ATR-FTIR Spectrosld have proved difficult to detect through the use of traditional, gravimetric analysis. NMR characterization of aliquots revealed a reversible, chain end dehydrochlorination reaction, which occurs at low monomer conversions. In situ NMR experiments were conducted to further the mechanism of this reaction.

In Situ NMR Monitoring of Living Radical Polymerization,ne glycol containing macroinitiators. The .H NMR study of the catalyst complex in the presence of ethylene glycol groups leads us to conclude that there is possible competitive co-ordination at the copper between ligand and ethylene glycol groups. This influences the Cu(I) / Cu(II) equilibrium, resulting in the high observed polymerization rate.

Investigation of High Temperature Isobutylene Polymerizations Utilizing Real-Time ATR-FTIR Spectrosed using in situ ATR-FTIR spectroscopy (ReactIR 1000, ASI Applied Systems,Inc.). The polymerizations were carried out in chlorinated solvents with boron trichloride as Lewis acid catalyst, and in the presence of the Lewis base (LB)2,4-lutidine, 2,6-lutidine, or 2,6-di-tert-butylpyridine, or the comm

Kinetic Study of Photoinitiated Polymerization Reactions by Real-Time Infrared Spectroscopy,nomer conversion . time curves have been recorded in systems where the liquid to solid phase change occurs within seconds. Some important kinetic parameters have been determined for such ultrafast reactions namely the kinetic chain length, the growth rate of polymer chains and the rate constants of
