Abstract

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.

Key words: Microgel core/shell polystyrene microparticle, Separation of linear PS, TLC, GPC, TLC scanning
