포스터 발표 - 고분자공업분과 : PolyHEMA ( poly ( 2- hydroxyethyl methacrylate ) ) Beads 제조에 관한 형태학적 연구
임재홍,허형회,김환기,한학수,김중현,조영일 ( Jae Hong Im . Hiung Hoi Hur,Whan Gi Kim,Hak Soo Han,Jung Hyun Kim,Yung Il Joe ) 한국공업화학회 1997 한국공업화학회 연구논문 초록집 Vol.1990 No.3
N/A We investigated the effect of 1-octhanol and PVP(poly(N-vinyl-2-pyrrolidon) K-90) on the changes of shape, size distribution, porosity of PolyHEMA beads, which were prepared by suspension polymerization. As the concentration of 1-octhanol increases, the shape of PolyHEMA beads becomes irregular and the average size of the beads grows. Also the porosity and the average radius of PolyHEMA beads are increased. Increased PVP concentration makes average radius small but the effect can be ignored when the concentration is over 3 %. The porosity gets a gains of nearby 25 % as its concentration increases. But it does not affect on the shape.
