assembling a bunch of transition metals oxides on sodium montmorillonite layer for anionic polymerization of butyl methyl acrylate

In the present study, anionic polymerization of butyl methyl acrylate has been carried out in oxygen atmosphere over different heterogenic prepared catalytic systems which are composed of a group of three metal oxides ( ti, mn cu ) assembled on thin layers of clay ( bentonite ) as hydrogenating/dehydrogenating activation for the polymerization reaction. the prepared catalysts and polymeric products were distinguished by different spectroscopic techniques such as xrd, 1hnmr, energy-dispersive x-ray spectroscopy (edx), scn, tem, ir, and gel permeation chromatography (gpc). we deduced that the dimensions of the efficiency of each catalyst as well as whole composites on the polymerization of butyl methyl acrylate of process, also, we approach the reaction mechanism of the polymeric process, furthermore, studying the variation and factors affecting on anionic polymerization like polydispersity index and tactility properties, more details and discussion were deeply investigated blow throughout the analysis and data analysis.
