✦ Synopsis


Decomposition of polyprop.~lenc hydroperoxide in styrene with triethylenetetramine, diethylenetriamine and ethylenediamine at 23-80-was studied by electron paramagnetic resonance measurements. The hfs parameters for isotropic EPR spectra of aminoalkylnitroxy radicals from these polyamines were determined. The supposed complex formation of polymeric hydroperoxide with polyamine by two hydrogen bondings facilitates its decomposition with styrene.

An on-line electron spin resonance (ESR) technique was applied to investigate the syndiospecific polymerization of styrene activated by the catalyst system CpTiCl 3 /MMAO. The measurements included trivalent titanocene concentration and monomer conversion. The activation procedure was found to have
