Poly(ally1benzene)s were synthetised by Ziegler-Natta catalysts: [VCl, + Al [CH,CH(CH, ) , 1, ] and [TiC14 + Al [CH2CH(CH,)2I3]. Two different polymers were obtained. Examination of their microstructures by IR and 'H 13C NMR spectroscopy suggests that one of the polymerization mechanisms proceeds vi

Tensile creep tests with durations of 90-120 min were performed on several different types of graphite over the temperature range of 2300 to 2900°C. For ATJ graphite, the creep rate was found to vary with the fourth power of the stress on specimens oriented both "with-the-grain" and "against-the-gra

A new and efficient synthesis of 1-ethoxyphosphindole oxide l i s reported. The dipolarophilic activity of this heterocycle towards three class of 1,3-dipoles was tested. The cycloaddition reactions are regio-and stereospecific. Nmr data PH and 13C) allow us to determine the regio and the diastereoc
