Claim 5:
6. The method for producing a shaping material according to claim 1, wherein the content ratio of a compound that has a boiling point of lower than 200° C. with respect to the whole shaping material is 3 ppm or less in terms of n-decane when components of the shaping material are analyzed by the following dynamic headspace-gas chromatography/mass spectrometry:
a sample container composed of a glass tube having an inner diameter of 4 mm, in which 100 mg of the shaping material is charged, is connected to a gas collection tube that have been cooled by liquid nitrogen, and then the sample container is heated at 200° C. for 30 minutes in a high-purity helium stream, followed by continuously collecting gas released from the shaping material into the gas collection tube; and
the collected gas is subjected to thermal desorption-gas chromatography-mass spectrometry using n-decane as an internal standard, and the amount of the gas released from the shaping material is calculated in terms of n-decane.
