Abstract
A ceramic composition which can be extrusion or injection molded to ceramic greenbodies comprises a sinterable powder mixed within a polyacetal binder and further includes a dispersing aid comprising a polyester oligomer formed by self condensation of a hydroxy fatty acid in which the hydroxy group is attached to an internal carbon atom of the fatty acid. The dispersing aid also acts as a stabilizer for the polyacetal binder during compounding with the powder.
