The reaction of α,α′-dibromometaxylene (DBMX) with sodium cyclopentadienide (CpNa) gives several oligomers, which were characterized by Size Exclusion Chromatography (SEC) and Liquid Secondary Ion Mass Spectroscopy (LSIMS). The obtained oligomers came from two competitive mechanisms after an anionic substitution of the DBMX by CpNa. The first was based on the proton transfer between the monosubstituted...
Reaction between benzylbromide and sodium cyclopentadienide leads to a mixture of dienes. These can be identified by several techniques such as size exclusion chromatography, mass spectroscopy (MS) and high performance liquid chromatography/MS coupling. Their structure is confirmed by analysis of adducts obtained after reaction of N-(4-benzoyl)-phenylmaleimide with these dienes.
The thermal polymerization of arylacetylene compounds has been studied from a monofunctional model compound, 4-(hexyloxy)phenylacetylene I. I was synthesized and bulk polymerized under several experimental conditions. The reaction products were analysed by chromatography, spectroscopy and spectrometry techniques. The observed average polymerization degree is low. The lowest molecular weight compounds...
Four linear dimers of 4-(hexyloxy)phenylacetylene I have been synthesized and thermally polymerized under the same conditions which were used for I. The polymerization of monomer and linear dimer mixtures as also studied. The reaction products were analysed by chromatography, spectroscopy and spectrometry techniques. The experimental results led us to conclude that the linear dimers are not reaction...
