  • 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 $53.6^{\circ}C$.

  • In order to improve the low impact resistance of polystyrene without harming its transparency the styrene monomer was copolymerized with transparent butyl acrylate (BA), and methylmethacrylate (MMA) to obtained a poly(styrene-co-butylacrylate) P(SM-co-BA) and a terpolymer copolymer P(SM-co-BA-co-MMA). The polymers were then cross-linked with the aid of a cross-linking agent dicumylperoxide (DCP), and their mechanical and optical properties were tested. It was found that the contents of monomers and DCP affect the mechanical, thermal, and optical properties of the polymers. An increase in BA contents in P(SM-co-BA) and P(SM-BA-MMA) improved the mechanical strength, but the optical properties remained the same with some exception for P(SM-co-BA). An increase in the DCP contents improved the mechanical but found losses in the optical properties.

  • The coating material for the ink-jet printing paper tends to be waterbase as the waterbase ink-jet ink is used more widely. Waterbase coating material consists of alumina sol as a pigment, poly(vinyl alcohol) as a main binder and polymeric additive for improving properties. In this study, polymeric auditive was synthesized by combining one or toto monomers among methacrylic acid, acrylic acid and acrylamide to the basic monomers, styrene and n-butylacrylate. The properties of printability such as ink absorption, ink spreading, and optical density, glossiness and water resistance were investigated by changing the kinds of surfactants, the composition of monomers and the structure of polymer particles. Results showed that materials containing anionic surfactant and/or acrylic acid had problems in com-patibility with alumina sol. Also, coating materials containing acrylamide had good printability and lout glossiness while those containing methacrylic acid did not have good printability and high glossiness.
