$\varepsilon$-Caprolactame as organic monomer was intercalated in the interlayer space of montmorillonite and polymerized by polymerization reaction so that the inorganic polymer and organic polymer could be combined each other by chemical bonding. The results of X-ray and IR analysis showed that the polymerization reaction of $\varepsilon$-caprolactame between the interlayer spaces has been performed sucessfully. In order to study polymeric reaction product in detail we have isolated the polymerized material from the interlayer space and analyzed it by X-ray diffractometer and IR-Spectrocopy. The comparison of these results with them of the analyses for thee pure polymer which has been synthesized by polymeric reaction of $\varepsilon$-carolactame without montmorillonite showed that the obtained both polymeric materials are the same compounds.

In this research [RCOOH]-$\varepsilon$-Caprolactam-Montmorillonite was synthesized by reaction between Na-Mont-morillonite (10-Carboxy-n-decyl)dimethylethylammonium (=RCCOH) ion and $\varepsilon$-Caprolactame-Motmorillonite ob-tained was 3.62$\AA$ After heat treatment of this intercalations complex at 37$^{\circ}C$ in high vacuum for 12 h 24 h, 40 h and 90 h the basal spacing was reduced to 35.8$\AA$, 34.2, 17.5 $\AA$ and 16.6$\AA$ respectively. The calculated amount of free $\varepsilon$-caprolactame included int he intercaltions complex and that of $\varepsilon$-caprolactame which is interca-lated into the interlayer space of montomorillonite and still remained after heat treatment are 4.6~4.9 and 0.5 molecules per unite cell of montmorillonite respectively.
