Abstract: The X-ray crystallinity and the isotactic index [II(%)] values were measured for polypropylene (PP) samples prepared by VOCl3 and various aluminum alkyls. The reaction parameters, such as aging time, temperature, reaction medium, and additives, have some effect on the crystallinity of the samples. Among the three systems studied, a combination of VOCl3 + Et2AlCl was found to give PP with higher crystallinity and II. In general, the tacticity of the samples prepared were much lower than the samples prepared with alpha-, beta-, gamma-TiCl3 as the catalyst.
