| Outline of Final Research Achievements |
Poly (N-isopropylacrylamide-co-2-hydroxyethyl methacrylate) (P(NIPAM-co-HEMA)) was synthesized using ultrasonic irradiation in a mixed solvent of water and ethanol without chemical initiator. Effects of operational factors such as the monomer molar ratio and ultrasonic power intensity on time courses of the conversion ratio, the number average molecular weight, the polydispersity, and the copolymer composition of the synthesized polymers were investigated in order to determine the optimum conditions to synthesize the temperature-responsive polymer with low molecular weight distribution (i.e., low polydispersity). According to the experimental observation, a kinetic model for copolymer synthesis process under ultrasound was also constructed. The kinetic model can explain the experimental results of the conversion ratio, the number average molecular weight, the polydispersity, and the copolymer composition.
