摘要：

Group-transfer polymerization was used to make block and random copolymers of methacrylates with a small fraction of methacrylic acid units. These polymers bind strongly to aluminum oxide surfaces through the acid groups and act as efficient dispersants for alumina particles in polar organic solvents such as esters and ketones. The dispersion efficiency was measured by the sediment density method as a function of chain length and composition. Ceramic green tapes and sintered ceramic sheets were made using these dispersants and poly(butyl methacrylate) as a binder.
