Synthesis of polycalciumphenylsiloxane and composites based on the skeleton of a sea urchin with the resulting polymer

In this work, we obtained polycalciumphenylsiloxane (PCPS) by the interaction of calcium bis (acetylacetonate) with polyphenylsiloxane. The first method consisted in boiling starting reagents toluene for several hours; second was as follows: mixture preliminarily treated mechanically a ball mill, followed hours. Two fractions, soluble and insoluble, were isolated both syntheses. They investigated using IR, NMR spectroscopy, thermogravimetric analysis, gel permeation chromatography. It shown that insoluble fraction is acetylacetonate polyphenylsiloxane small ion content. polycalciumphenylsiloxane. yield higher synthesis method. polymers methods are similar composition structure, which confirmed physicochemical methods. Next, skeleton sea urchin Strongylocentrotus intermedius toluene. case, composite obtained, 2–3% hydrochloric acid then calcined at temperature 600 °C. At each stage, composites elemental analysis IR spectroscopy. morphology scanning electron microscopy.
