초록

본 연구에서는 유기현탁제로 폴리비닐알콜(PVA: Poly(vinyl alcohol)을 사용하여 현탁중합토너를 제조하였다. 스타이렌과 부틸아크릴레이트 모노머를 동시에 사용하고 카본블랙을 첨가하여, 좁은 입경분포를 갖는 미세 구형 중합토너를 제조하였다. 최적의 현탁중합조건을 설정하기 위하여 카본블랙이 배제된 예비입자 중합실험을 먼저 수행하였다. 예비입자는 다양한 중합조건에서 제조하였으며, 각각의 특징을 비교 분석하여 최적의 중합조건을 결정하였다. 최적화된 중합조건을 선택하여 제조된 흑색중합토너는 입경 및 형상이 우수하였으며 유리전이온도도 $53.6^{\circ}C$인 것으로 나타나 열적 특성 및 인쇄특성도 우수한 것으로 관찰되었다.

In this study, suspension polymerized toners were prepared by using poly(vinyl alcohol)(PVA) as an organic suspending agent. Styrene and butylacrylate monomers were used simultaneously with carbon black to prepare microspherical polymerized toners with a narrow-particle size distribution. Preliminary particles without carbon black were polymerized first to optimize suspension polymerization conditions. The preliminary particles were prepared at various polymerization conditions and their characteristics were compared to each other to determine an optimized polymerization condition. The black polymerized toner prepared at the optimized polymerization condition showed reasonable particle size and shape, and good thermal and printing characteristics by showing its glass transition temperature at $53.6^{\circ}C$.
