Abstract
The Piezoelectric Quartz Crystal Microbalance (QCM) method was used to measure the solubilities of n-amylalcohol in poly (n-butyl methac1ylate) and polyisobutylene at temperatures of 333.15 K, 353.15 K and 353.15 K. The crystals used were 5 MHz, AT-Cut, 5.5 mm in diameter and 0.3 mm in thick. Reliability of the measurements was comfirmed by comparing the present data with the literature data for the system of benzene-polyisobutylene at temperature 338.15K. The solubilities n-amyl alcohol in polyisobutylene were undectedable in the range of temperature experiments by the present apparatus because of the low solubility. For the solubilities of n-amyl alcohol in ploy (n-butyl methacryalate) the higher temperature, the lower solubility and the experimental data could be correlated by the UNIQUAC equation with average absolute deviation between experimental and calculated solvent activities of 3.8%.

采用压电石英晶体微天平(QCM)法测定了正戊醇在聚甲基丙烯酸正丁酯和聚异丁烯中的溶解度,温度分别为333.15 K、353.15 K和353.15 K。所用晶体为5mhz, AT-Cut,直径5.5 mm,厚0.3 mm。通过与文献中苯-聚异丁烯体系在338.15K温度下的数据对比,证实了测量结果的可靠性。由于正戊醇在聚异丁烯中的溶解度较低,本装置在温度实验范围内不能测定其溶解度。对于正戊醇在聚甲基丙烯酸正丁酯中的溶解度,温度越高,溶解度越低,用UNIQUAC方程计算得到的结果与实验结果的平均绝对偏差为3.8%。关键词:溶解度,石英晶体微天平,溶剂,聚合物摘要:penelitian ini, mede压电式石英晶体微天平(QCM) digunakan untuk mengukur kelarutan pelarut n-淀粉醇dam聚合物聚(甲基丙烯酸正丁酯)聚异丁烯pada温度333,15 K, 343,15 K, 353,15 K。Kristal yang digunakan adalah jenis AT-Cut 5 MHz,直径5.5 mm dan ketebalan 0.3 mm。可靠性:达里企鹅和登根企鹅的数据文献:苯-聚异丁烯体系温度:338,5k。Kelarutan n-amyl对于酒精dalam聚异丁烯有些dapat terdeteksi篇范围温度eksperimen dengan peralatan杨ada林嘉欣kelarutannya rendah。Untuk kelarutann - amyaldalam聚甲基丙烯酸正丁酯,semakin besar suhu, kelarutannya semakin rendah数据,实验数据dapat dikorelasikan menggunakan persamaan UNIQUAC dengan rata-rata deviasi ahsolut sebesar 3,8%。Kata Kunci:克拉鲁坦,石英晶体微天平,Pelarut,聚合物
