Preparation and Structure Control of Poly(butyl acrylate)/Poly(methyl methacrylate) Core/Shell Impact Modifier
Abstract:
Poly(butyl acrylate)/poly(methyl methacrylate) core/shell impact modifiers were prepared by seeded emulsion polymerization. The structures of the modifiers have been designed and the factors affecting the structure formation have been discussed. In order to inhibite the formation of new particles during seeded polymerization, an oil-soluble redox initiator was used and the concentration of the emulsifier and feed speed of the monomer were controlled. The results showed that the particle size of the impact modifier can be adjusted by varing the amount of seed emulsion used in the seeded emulsion polymerization. TEM micrographs showed that the impact modifiers are monodisperse particles of spherical structure.
