The film formed by the resulted co re-shell emulsions has very excellent opaque property and good whiteness, which can be improved by increasing the water-absorbing ability of the core polymer and enhancing the T g of the shell polymer.

• 该核壳乳液成膜后得到的聚合物膜具有良好的遮光性能 ,且聚合物的遮光性随核聚合物吸水性能的提高而提高 ,同时壳层聚合物的 Tg 越高 ,膜的遮光性能越大。
