Classification: CPC B  C | IPC B  C

Claim 1:
2. The method for producing a shaping material according to claim 1, wherein a content ratio of a compound that has a boiling point of lower than 200° C. with respect to the whole raw-material resin is 15 to 50 ppm in terms of n-decane when components of the raw-material resin 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 raw-material resin 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 raw-material resin 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 raw-material resin is calculated in terms of n-decane.
