In DSC (differential scanning calorimetry) thermograms in addition to general features characteristic of γ-irradiation cross-linked crystalline polymers, a typical cold-crystallization phenomenon was observed during the sceond scan for samples that had been subjected to high radiation dose. G-values for crosslinking nylon 610 were estimated from gel fraction measurement and TMA (thermomechanical analysis), From TMA curves it was estimated that the dimensional stability of properly irradiated nylon 610 articles might be raised up to ca. 300℃. 收起
