本文之目的,乃探討兩種特用添加劑,分別為:(1)奈米級與次微米級核殼型橡膠(core-shell rubber)添加劑及(2)蒙特納石黏土(montmorillonite clay,MMT),其對苯乙烯/不飽和樹脂/特用添加劑三成份系統,其聚合固化後成品之微觀型態結構、抗體積收縮特性及內部可染色性、機械性質等之影響。實驗之結果,吾人將配合苯乙烯/不飽和聚酯樹脂/特用添加劑三成份系統在未反應前之相容性,x光散射分析、固化樣品之微觀結構、聚合固化後之反應轉化率及微孔洞體積分率等因素之整合性實驗測量結果加以解釋。
接著吾人再利用小角度X-ray散射儀(SAXS)測量不飽和聚酯(UP)之稀薄苯乙烯(St)溶液之散射強度,再根據Guinier Law計算不同UP之環動半徑(Radius of Gyration),而針對於St/UP/MMT三成份系統,為瞭解UP分子擴散至蒙特納石黏土(MMT)層間之難易程度,吾人亦以小角度X-ray散射儀(SAXS)及廣角度X光散射儀(WAXS)測定及苯乙烯(St)/不飽和聚酯(UP) /MMT三成份系統在聚合固化後不同濃度下之散射強度與散射角度,以瞭解蒙特納石黏土加入不飽和聚酯(UP)與苯乙烯(St)溶液後之奈米黏土層間距離及材料內部結構在聚合固化後之變化情形。


The effects of two additives, including (1) nano- scale and submicron-scale core-shell rubber additive, and (2) montmorillonite clay, on the cured sample morphology, volume shrinkage characteristics and internal pigmentability, mechanical properties of the styrene(St)/Unsaturated Polyester(UP)/additives ternary systems after the cure have been investigated. The experimental results have been explained by integrated measurements combining phase characteristic of the St/UP/additive ternary system before the cure, XRD analysis , cured sample morphology, final cure conversion, and volume fraction of microvoid generated during the cure by using DSC , SAXS , WAXS , SEM , TEM , OM and image analysis.
Then the scattering intensity of unsaturated polyester (UP) with different structure in dilute styrene solution was measured by the method of small angle X-ray scattering (SAXS), and the radius of gyration of the UP molecule can then be calculated by using the Guinier law. For St/UP/ silane-treated MMT ternary systems, I try to calculate the gallery spacing change of MMT clay by intensity of different concentration cured samples.
