Study on Synthesis Technology and Recipe Optimization of Core (PBA) - Shell (PMMA) Latex Particles

Abstract:

In this paper, a novel grafting poly(butyl methacry1ate)-poly(methyl methacrylate) (PBA/PMMA) latex particles with core-shell structure was successfully synthesized by the method of pre-emulsion semi-continuous seeded emulsion polymerization. PMMA shell layer was cross-linked structure, and it was almost grafted onto PBA core due to the presence of the grafting agent ALMA. The influences of the amount of emulsifier and initiator, and reaction time on PBA core emulsion properties were investigated by analyzing BA conversion and PBA core particles size distribution. The influence of the amount of grafting agent on the polymerization system was also discussed by determining BA conversion and the gel content of PBA core emulsion. PBA/PMMA latex particles were characterized by laser particle size analyzer, transition electron microscopy (TEM).
