本文旨在藉由實驗觀察聚甲基丙烯酸酯在甲醇溶劑內因為質傳所產生之物理與化學變化，並探討如何利用此一現象來進行高分子加工成形。實驗結果顯示把聚碳酸酯/聚甲基丙烯酸酯/聚碳酸酯三明治結構（其中外層之聚碳酸酯上下給予對位及鑽洞）垂直浸泡在60℃甲醇中進行雙向質傳，甲醇質傳到聚甲基丙烯酸酯引發其產生膨潤，但此時孔洞周圍之聚碳酸酯對膨潤之聚甲基丙烯酸酯則產生拘束應力，使其膨潤形成圓弧曲面；當聚碳酸酯孔洞直徑小至3mm時，則圓弧曲面會從單圓弧曲面變成雙圓弧曲面。另外，使用60℃甲醇給予單向質傳到三明治結構，但其中一面的聚碳酸酯孔洞給予遮蔽，則其單圓弧曲面之高度及曲率則較雙向質傳小。 The purpose of this study is to investigate experimentally thechemical and physical changes due to mass transform between PMMA andMethanol and how to utilize the results in the polymer processing. Experimental results demonstrate that when the sandwich structure ofPC/PMMA/PC (the three layers were aligned and a hole was drilled onthe two outer layers) was immersed in Methanol for several hours, PMMAexpands due to the mass transform of Methanol, but because theboundary was constrained by the structure, a convex surface wasformed. If the diameter of the hole was smaller than 3mm, then adouble -convex surface was formed. It was also found that if the holewas drilled only on one side, a convex surface was formed and theheight and curvature of it were less than that of the double- convexsurface.
