    • A plastic window panel for an automotive vehicle comprises a plastic panel of a transparent noncrystalline organic high polymer. Silica particulate is dispersed in the plastic panel and has a particle size not larger than wavelengths of visible light. The plastic window panel is produced by one of a first method and a second method. The first method comprises (a) providing a first solvent in which the silica particulate having the particle size not larger than wavelengths of visible light is dispersed, and a second solvent in which the transparent noncrystalline organic high polymer is dissolved; (b) mixing the first solvent and the second solvent to obtain a resin composition; and (c) molding the resin composition under heating. The second method comprises (a) providing the silica particulate having the particle size not larger than wavelengths of visible light; (b) mixing the silica particulate into the organic high polymer which is in a process of formation of the organic high polymer, to obtain a resin composition; and (c) molding the resin composition under heating.
    • 用于机动车辆的塑料窗板包括透明非晶有机高分子聚合物的塑料面板。 二氧化硅颗粒分散在塑料面板中,其粒径不大于可见光的波长。 塑料窗板由第一种方法和第二种方法之一制成。 第一种方法包括(a)提供其中分散有不大于可见光波长的粒径的二氧化硅颗粒的第一溶剂和溶解有透明非结晶性有机高分子的第二溶剂; (b)混合第一溶剂和第二溶剂以获得树脂组合物; 和(c)在加热下成型树脂组合物。 第二种方法包括(a)提供粒径不大于可见光波长的二氧化硅颗粒; (b)将二氧化硅颗粒混合到形成有机高分子的过程中的有机高分子中,得到树脂组合物; 和(c)在加热下成型树脂组合物。
