Abstract
A new coagulation method which consists of two stages the generation of seed particles and growth of particles, was developed for the preparation of pellet-like particles from polymer latex.
In this report, first the mechanism of this coagulation was studied through an examination of the coagulating velocity during each stage. Then, the pellet-like particles were characterized by a SEM observation of the inside of a particle and measurement of particle properties.
As a result, experimental equations on the amount of generated seed particles and rate of growth of the particles were obtained. The phenomena in which the latex particles inside the coagulated particle are packed closely by drying and are fused homogeneously by sintering, was confirmed.
