碩士 === 國立臺灣科技大學 === 化學工程系 === 103 === The object of this study was to prepare Microgels latex by miniemusion copolymerization with MMA and EGDMA monomer. In addition to changing the reaction temperature, but also compare to P-MMA and P-EGDMA. In addition, overall conversion, monomer conversion, colloid diameter were used to investigate the relationship between monomers and particle nucleation mechanism. DSC, TGA, FTIR, NMR,TEM,GPC used to investigate the Structure of Microgels and properties of Microgels. Finally , Microgels were dissolved at solvent ,and figured out the changing of the rheological property. Besides ,Ostwald Ripening Effect, creaming line , Phase separation were used to discuss latex stability.
