| Summary: | 碩士 === 淡江大學 === 化學工程與材料工程學系碩士班 === 104 === In this research, we investigate polymeric particles consisting two principal constituent monomers, of which one is electrolyte with sulfonic acid group: 2-Acrylamido-2-methyl-1-propane sulfonic acid (AMPS), and the other is multi-vinyl: 1,1,1-Trimethylolpropane triacrylate (TMPTA) were successfully synthesized by photoinitiated precipitation polymerization with 2-hydroxy-2-methylpropiophenone (UV1173). Synthesis was found to be composed of two stages. The early precipitation polymerization leads to the formation of nuclei. Subsequent emulsion-assisted polymerization permits the formation of electrolytic shell part over the core. The particle composition was revealed by FTIR, and the characterization of particle size was effectuated by both DLS . IR spectrum as shown below confirms that TMTPA(n ̅= 1732 cm-1, ester C=O) and AMPS(n ̅= 1040 cm-1, symmetric stretching sulfonic SO3- hydrated) both constitute significantly the particle. The particle size was measured to be about 200-300 nm by DLS.
