Abstract
Ceramic compositions comprising a ceramic material such as alumina, clay, a dispersant and a polymeric binder are prepared using as the polymeric binder a connected branch copolymer comprising a core segment, non-crosslinked branched polymer segments attached to the core segment and linear polymer segments connected to the branched polymer segments and bearing terminal groups capable of effecting hydrogen bonding. By using this form of polymeric binder, polymers of relatively high molecular weight can be used, thereby giving good green strength in the greenware, while still keeping the slurry viscosity relatively low.
