摘 要：正Newly synthesized oligomers have been designed with excellent pigment wetting characteristics. The rheology and kinetic stability of pigment dispersions, prepared by either media or three roll muling various pigments in each resin system, will be compared. The ease of dispersion, probed by monitoring the pigment particle size distribution as a function of milling, is dependent on the chemical nature of the oligomer. Oligomers based on polyester and acrylic chemical backbones will be highlighted since they possess superior flow at higher pigment loading versus epoxy or urethane acrylates. In addition, the physical properties of cured polymer films of the different oligomers will also be evaluated and compared.
