Na-Montmorillonite와 10-Carboxy-n-decyltriethylammonium bromide (유기 양이온) 사이의 양이온 교환반응에 의해 얻어진 [TEACOOH]-Montmorillonite 층간화합물을 유기 단분자인 $\varepsilon$-caprolactone을 반응시켜 [TEACOOH]-$\varepsilon$-caprolactone-Montmorillonite 층간화합물을 형성하였다. 이렇게 얻어진 [TEACOOH]-$\varepsilon$-caprolactone-Montmorillonite 층간화합물을 $220^{\circ}C$의 온도 하에서 48시간 동안 가열하여 고분자화시켜 무기물질인 몬모릴로나이트와 유기 고분자인 폴리카프로락톤이 화학적으로 결합된 몬모릴로나이트/폴리카프로락톤 나노복합재료를 제조하였다. 고분자화반응을 수행한 후 얻어진 시료를 메탄올을 이용하여 추출한 뒤 고진공 하에 $65^{\circ}C$로 24 시간 동안 건조시킨 후에 얻은 층간거리 값으로는 34.24 $\AA$이 얻어졌다.

In this research an organic cation, [TEACOOH] Br, with a long alkyl chain was synthesized which will replace the metal ion between the layers of Na-Montmorillonite and an organophilic [TEACOOH]-Montmorillonite intercalations complex was formed by the cation exchange reaction between the Na-Montmorillonite and the synthesized [TEACOOH] Br. After drying of this intercalations complex in high vacuum we have tried to experiment on the probability whether it will form complexes with various swelling solutions such as dist. water, methano, ethanol, toluene, acetonitrile and propionitrile and the corresponding basal sp acings measured were $17.41{\AA}$, $31.90{AA}$, $34.42{AA}$, $30.52{AA}$ and $32.36{AA}$, respectively.

A [TEACOOH]-Montmorillonite intercalations complex obtained from Na-Montmorillonite and 10-Carboxy-n-triethylammonium bromide was used to attempt the polymerization of ${\varepsilon}$-caprolactone between the layer spaces of the intercalations complex to achieve Montmorillonite-Polycaprolactone nanocomposites in which the inorganic material (montmorillonite) is chemically combined with the organic polymer (polycaprolactone). The results of X-ray-, IR-, and TEM-analyses for samples obtained after polymerization showed that a polycondensation reaction was successfully produced. For a more precise investigation of the polymeric reaction products the polymerized products were separated from the silicate layers and analyzed with an IR-spectrometer. A comparison of the results of the IR-analyses of the separated polymer with that of the polymer synthesized by the reaction of ${\varepsilon}$-caprolactone with only the organic cation and without montmorillonite showed that the two obtained polymers are the same compound.
