| titleOfInvention | Acryl Microbead Having Marron Particle Size Distribution and Method of Preparing Thereof |
| abstract | Disclosed herein are acryl microbeads having a narrow particle size distribution and a method of preparing the same. In a method of preparing acryl microbeads through polymerization by stirring a polymerization composition containing vinyl acrylate monomers, an initiator and a dispersion stabilizer at a high speed to form microdroplets and increasing a reaction temperature to induce the polymerization reaction of the monomers within the microdroplets, a low molecular weight seed particle capable of absorbing vinyl acrylate monomers dissolved in a reaction medium outside the microdroplets is supplied at the time of the polymerization reaction, and thus the acryl microbeads have a narrow particle size distribution. The microbeads, which are almost completely free of fine and coarse particles and thus need no sorting process, which range in size from 1 to 50 μm, and which have a narrow particle size distribution can be prepared at a high yield without using a polymerization inhibitor. Exhibiting excellent physicochemical properties including color, transparency, etc., the microbeads can find a wide spectrum of applications in various industries including optical, cosmetic, and food industries. |
