摘要： 本文用薄层色谱成功地将微交联核-壳结构聚苯乙烯微粒中的少量线性PS分子与微交联组分相分离,用凝胶色谱法测得线性PS的分子量为104～105数量级;0.2～1.6×10-6g的点样量,薄层扫描吸收峰面积与样品量成良好的线性关系;可直接由峰面积计算线性PS分子的含量;结合微粒的表观粘度,对微粒的核-壳结构进行了定性分析。

Abstract: Thin-layer chromatography(TLC) and GPC were used to analyze linear PS in the mi-crogel core/shell polystyrene microparticle.Linear PSwas separated from crosslinking component by TLC, its molecular weight (MW) is 104～105 by GPC.The content of linear PSin the sample can be calculated directly with the area value of TLCscanning, when the weight of the sample was controlled under 1.6× 10-6 g; Combining the MW and content of linear PS with apparent viscosity of the sample, structure of the particles was analyzed qualitatively.
