摘要

Polymethylmethacrylate particles with narrow size distributions with different sizes in the range of 1.25-4.58 mu m were produced by dispersion polymerization of methylmethacrylate (MMA) in ethanol/water media, by using 2,2'-azobisisobutyronitrile (AIBN) (as an initiator), (PVP) poly(vinyl pyrrolidone) (as a stabilizer), and eerie ammonium nitrate (CAN) (as a coinitiator and also as a costabilizer). Particle size was increased by increasing the initiator concentration and the ethanol : water ratio, and by decreasing the monomer : dispersion medium ratio and the PVP and CAN concentrations. The addition of CAN in the recipe of the MMA polymerization improved the monodispersity, and also increased the monomer conversion rate. (C) 1996 John Wiley & Sons, Inc. [References: 33]
