摘要：
PURPOSE: A hemispherical polymethylmethacrylate beads is provided to have a high adhesion and oil absorption, to easily control the size thereof, and to be manufactured by a large amount. CONSTITUTION: A hemispherical polymethylmethacrylate beads has a hemispherical shape. The hemispherical polymethylmethacrylate bead has a tap density of 0.1-0.5 g/ml and an oil absorption of 2.4-3.0 cc/g. A manufacturing method of a hemispherical polymethylmethacrylate bead comprises a step of conducting a polymerization reaction by putting an acrylic monomer, a crosslinking agent, an initiator, and a cosolvent into a solvent, conducting a polymerization reaction, and cleaning and drying the result. The boiling point of the cosolvent is (-5)-15 °；C.본 발명은 반구형 폴리메틸메타크릴레이트 비드에 관한 것으로, 본 발명의 반구형 폴리메틸메타크릴레이트 비드는 화장품, 의료용품, 생활용품, 디스플레이 용품, 조명기구 및 잡화에 적용시 높은 점착성 및 흡유량을 가지며, 특히 화장료에 적용시 구형 폴리메틸메타크릴레이트 비드에 비하여 더욱 화사한 색감을 가지게 할 수 있다.
