本文探討核心為PBA(聚丙烯酸正丁酯)，外殼為PMMA之奈米級及次微米級壓克力核殼型橡膠(CSR)及兩種特用添加劑，其對苯乙烯(St) / 不飽和聚酯(UP) / 特用添加劑其三成份系於聚合固化後成品之機械性質的影響。
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，吾人利用小角度X-ray散射儀(SAXS)測定不飽和聚酯(UP)之稀薄苯乙烯(St)溶液之散射強度，再利用Guinier Law計算UP之環動半徑(Radius of Gyration)。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前後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前及在聚合固化後之變化。

In this work, the effects of nano-scale and submicron-scale acrylic type of core-shell rubbers (CSR) and silane-treated montmorillonite (MMT) clay as additives for UP resins, on the mechanical properties of the styrene(St)/Unsaturated Polyester(UP)/additives ternary systems after the cure have been investigated.
For St/UP/ silane-treated MMT ternary systems,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. Hence, the ease at which the UP molecule can diffuse into the gallery spacing of the MMT clay can be evaluated.
The change of inter-gallery spacing of MMT and inter structure of the material for the St/UP/ silane-treated MMT systems before and after the cure has also been studied by using the SAXS and wide angle X-ray scattering (WAXS).
