The possible chemical interaction between synthetic hydroxyapatite or bovine enamel and a functional monomer of 4-methacryloxyethyl trimellitic acid (4-MET) diluted in methyl methacrylate (MMA) was examined by measuring the Raman spectra. It was concluded that the carboxyl group of 4-MET reacted with the calcium in the substrate to form a salt that was detected by the Raman band at around 1,380 cm-1. However, formation of the salt on the surface of the hydroxyapatite (HAP) with the carboxyl group, and polymerization of the 4-MET in the methacryl group near the surface were mutually exclusive reactions for the same 4-MET molecule.
通过测量拉曼光谱,研究了合成羟基磷灰石或牛牙釉质与稀释于甲基丙烯酸甲酯(MMA)中的4-甲基丙烯酰氧乙基偏苯三酸(4-MET)功能单体之间可能的化学相互作用。得出的结论是,4-MET的羧基与底物中的钙发生反应形成一种盐,该盐可通过拉曼谱带在1380 cm-1左右检测到。然而,对于同一个4-MET分子而言,羧基在羟基磷灰石(HAP)表面形成盐与甲基丙烯酸基团中4-MET在表面附近的聚合是相互排斥的反应。
