The studies on the application of the emulsions of poly(vinyl acetate-co-allyl ether)s containing nonionic hydrophilic poly(oxyethylene)
fragments as binders in the die pressing of alumina is presented. It was found that introduction of hydrophilic fragments
into molecules of a typical water dispersible polymer led to better polymer affinity to the ceramic powders. It was also shown
that low molecular mass of such copolymers should be relatively low ca 1500 g mol–1 to increase the density and thickening uniformity of the samples before and after sintering. The resultant sinters indicated
exceptionally high mechanical strength (bending strength ca 500 MPa).
