Abstract: The invention relates to a process for producing moulded articles by sintering crosslinked polyisocyanate polyaddition products with an average particle size of less than 0.25 mm in a mould at temperatures of 100 to 300@C and under a pressure of greater than 50 bar. The moulded articles produced according to the invention are thermally stable up to at least 150@C and possess a high hydrolysis resistance and solvent resistance.
