Abstract:
This paper uses the cluster dynamic method to simulate the morphological development of core-shell composite particle when the new clusters fromed on the surface of the seed. The experiment (results) of poly(vinyl acetate)(PVAc)/poly (butyl acrylate)(PBA) in the semi-continuous starved condition is as (a calculation) example, and the simulation results are consistent with the experiment results. The method proposed by this paper is suitable to the situation that the second stage monomer enters by semi-continuous starved condition in the two stages seeded emulsion polymerization.
