Abstract

The polymerization of $\varepsilon-caprolactone$ in the layers of the [DEACOOH]-Montmorillonite intercalations complex was attempted using 10-Carboxy-n-decyldimethylethylammonium bromide and Na-Montmorillonite to achieve [DEACOOH]-Polycaprolactone-Montmorillonite in which the inorganic material (montmorillonite) and the organic material (polycaprolactone) are chemically linked each other. The results of X-ray- and IR-analysis for the samples obtained after polymerization showed that the polymerization reaction has been successfully accomplished. In order to study the polymeric reaction products more precisely we have separated the polymerized product from the silicate layers and analyzed it with X-ray diffractometer, IR-spectrometer and TEM. The comparison of the results of X-ray- and IR-analysis for the separated polymer with them for the polymer which was synthesized by the reaction of $\varepsilon-caprolactone$ only with the organic cation without montmorillonite showed that the obtained both polymers are the same compounds.
