✦ Synopsis

Structural elucidation of acrylic-grafted polyester and the particle of its aqueous dispersion was carried out. The amount of the acrylics grafted to the polyesters was determined. The side chains grafted to the polyester were separated by the hydrolysis of the polyester segments. The structure of the acrylic-grafted polyester was estimated from the results of the characterization. Observation of the particles of the aqueous dispersion obtained from the grafted polymers was carried out, and it suggested that a shell layer existed on the particle. Dissolved states of each segment of the grafted polymer during the dispersing process were determined by 13 C nuclear magnatic resonance. Finally, the mechanism of particle formation from the grafted polymers was discussed.
