Manufacturing Quality Control of Dichlorodi-p-xylylene
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Molecular Weight and Distribution | Gel Permeation Chromatography (GPC) | Polymer molecules are separated through a chromatographic column. Number-average molecular weight (Mn), weight-average molecular weight (Mw), and polydispersity index (PDI) are calculated based on retention time to evaluate the uniformity of polymerization. |
| Monomer Residue Content | Gas Chromatography-Mass Spectrometry (GC-MS) | Residual monomers such as terephthalic acid and ethylene glycol are extracted from the sample, derivatized, and then quantified using GC-MS to ensure compliance with food/medical-grade safety standards (e.g., ≤10 ppm). |
| Thermal Stability | Thermogravimetric Analysis (TGA) | The change in sample mass with temperature under programmed heating is measured to determine decomposition temperature and residue content, assessing the material's heat resistance. |
| Melting Temperature | Differential Scanning Calorimetry (DSC) | Endothermic/exothermic peaks during heating of the polymer are measured to determine melting point (Tm) and crystallization temperature (Tc), evaluating crystallinity and purity. |
| Chlorine Content | Oxygen Bomb Combustion - Ion Chromatography (or X-ray Fluorescence Spectroscopy) | The sample is completely combusted, and chloride ions in the absorption solution are quantified by ion chromatography, or element chlorine content is directly determined by XRF, suitable for chlorinated polymers (e.g., PVC); however, terephthalate-based polymers do not contain chlorine, so this test is not applicable. |
| Moisture Content | Karl Fischer Titration | Iodine reacts quantitatively with water to precisely measure trace moisture in the polymer, preventing hydrolytic degradation during processing. |
| Appearance and Color | Visible Spectrophotometry / Visual Color Comparison | Transparency and yellowness index (YI) are evaluated by measuring absorbance at specific wavelengths for the sample solution or melt, or by comparing with standard color cards. |
| Mechanical Properties | Tensile Test (GB/T 1040) | Tensile strength, elongation at break, and elastic modulus are tested according to standard sample preparation to assess whether the mechanical properties meet requirements. |
| Ash Content | High-Temperature Incineration Method (550°C) | The sample is incinerated in a muffle furnace until constant weight, and the remaining inorganic residue is defined as ash, reflecting the presence of inorganic fillers or catalyst residues. |
