Electron spin resonance study of radical formation in cis-poly(phenylacetylene)/ferric acetylacetonate-triethylaluminum (PPA/Fe-Al). 2. Results and interpretation
Langner, Andreas; Ehrlich, Paul (The American Chemical Society: Macromolecules, 1990-04-19)The line-shape and saturation analysis for inhomogeneously broadened ESR spectra, developed in the previous paper, is used to study the change of the PPA/Fe-Al resonance signal with temperature and polymer aging. A mechanism ... -
The polymerization of phenylacetylene in carbon tetrachloride in the presence of light-activated W(CO)6
Park, S.; Serwon, S.; Langner, Andreas; Ehrlich, Paul (Wiley: Journal of Polymer Science Part A: Polymer Chemistry, 1989-12)A study of the apparent reaction rate constants of phenylacetylene polymerized in CCl4 in the presence of light-activated W(CO)6 and of the molecular weight of the resulting polymer indicates that the propagating centers ... -
Resolution and interpretation of the ESR spectra of polyphenylacetylene polymerized with ferric acetylacetonate and triethylaluminum.
Langner, Andreas; Ehrlich, Paul (Elsevier: Synthetic Metals, 1987-01)Features characteristic of triphenylcyclohexadienyl radicals formed in backbone cyclization, and of Al/Fe interactions are reported.
