Manufacturing method of polymer bead |
abstract |
The present invention is a multi-stage polymerization method in which a seed polymer is prepared by emulsion polymerization and then gradually polymerized using a monomer, a crosslinking agent, a reactive emulsifier, and a fat-soluble initiator. The final step relates to a process for producing polymer beads which do not use a crosslinking agent. According to the present invention, it is possible to provide a method for producing polymer beads having a particle size of 1 to 30 μm having excellent transparency and haze by improving the dispersibility with the thermoplastic resin in a form in which the crosslinked polymer is surrounded by an uncrosslinked polymerization site. . |
