ABSTRACT
[DEACOOH]-Montmorillonite intercalations complex obtained from Na-Montmorillonite and 10-Carboxy-n-decyldimethylethylammonium bromide (organic cation) was reacted with the monomer ($varepsilon$-caprolactone) to achieve the [DEACOOH]-$varepsilon$-caprolactone-Montmorillonite intercalations complex. From this intercalations complex Montmorillonite/Polycaprolactone nanocomposites in which montmorillonite (inorganic polymer) is chemically linked with the polycaprolactone (organic polymer) were formed at 240$^{circ}C$ by three different methods such as in stoichiometric amounts between monomer and organic cation, in excess of only the monomer and in excess of both organic cation and monomer. The products obtained after polymerization were analyzed with X-ray diffractometer and TEM.
Key words: [DEACOOH]-Montmorillonite intercalations complex, Na-Montmorillonite, 10-Carboxy-n-decyldimethyleth-ylammonium bromide, $\varepsilon$-caprolactone, Organic cation
