Abstract

The adsorption of methylmethacylate on layer silicates containing various interlayer cations has been studied by means of infrared spectroscopy and X-Ray. Several characteristic carbonyl bands of adsorbed methylmethacrylate appeared differently at the region of 1723∼1547$cm^{-1}$depending on the species of cation and the dehydration temperature. The carbonyl stretching band shifted about 190$cm^{-1}$ to lower frequencies has been observed only for polyvalent cations, which has been attributed to $>C=O{\cdot}{\cdot}{\cdot}M^{n+}$ complex formation. The band appeared at 1703∼1640$cm^{-1}$ is responsible for hydrogen bonding between carbonyl oxygen and cationic water or cationic hydroxyl group, and the degree of shift indicates good correlation with the polarizing power of the interlayer cations. However, the band appeared at 1723$cm^{-1}$ has not been correlated with the species of cation but assigned to the carbonyl stretching which reacted with the surface hydroxyl group. On the basis of interlamellar spacing, it is suggested that the molecular plane of MMA molecule is parallel to silicate layers.

여러 종류의 層間 陽이온을 가지고 있는 層狀 硅酸鹽上에서 일어난 methylmethacrylate의 吸着에 關하여 赤外線 分光法과 X-ray로 硏究하였다. 吸着된 methylmethacrylate의 여러 개의 特性 carbonyl band가 陽이온의 種과 脫水溫度에 따라서 다르게 1723∼1547$cm^{-1}$의 範圍에서 나타났다. 190$cm^{-1}$程度로 shift한 carbonyl 伸縮 band는 polyvalent 陽이온에만 나타났으며 $>C=O{\cdot}{\cdot}{\cdot}M^{n+}$型 着物形成 基因하는 것이었다. 1703∼1640$cm^{-1}$에서 나타난 band는 carbonyl 酸素와 陽이온 水 또는 陽이온 水酸基와의 水素結合에 依한 것이었고 shift한 정도는 層間 陽이온의 polarizing power와 좋은 相互 關係를 이루었다. 그러나 1723$cm^{-1}$에서 나타난 band는 陽이온의 鍾과는 相互 關係가 없었으며 carbonyl ,酸素와 表面 水酸基와의 相互 作用으로 因한 것이었다. Interlamellar spacing을 계산해 본 結果 methylmethacrylate의 分子平面은 硅酸鹽의 層과 平行하게 놓여 있는 것 같다.
