Manufacturing Quality Control of Poly(butylene terephthalate)
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Intrinsic Viscosity | Capillary Viscometry | Measures flow time of dilute polymer solution through calibrated capillary to calculate inherent viscosity related to molecular weight. |
| Acid Number | Acid-Base Titration | Determines free carboxylic acid end groups by titration with standardized KOH solution using phenolphthalein indicator. |
| Hydroxyl Number | Acetylation Titration | Quantifies terminal hydroxyl groups via acetylation with acetic anhydride followed by back-titration of unreacted anhydride. |
| Moisture Content | Karl Fischer Titration | Electrochemical titration using iodine, sulfur dioxide, and base in methanol to quantify water content based on stoichiometric reaction. |
| Ash Content | Gravimetric Analysis | Measures inorganic residue after complete combustion at 550-600 C in a muffle furnace, followed by weighing of residual ash. |
| Color (APHA) | Visual Spectrophotometry | Compares sample solution color intensity against APHA platinum-cobalt standard scale using spectrophotometer at 430 nm. |
| Melting Point | Differential Scanning Calorimetry | Detects thermal transition temperature during heating by measuring heat flow difference between sample and reference. |
| Residual Catalyst (Ti) | ICP-OES | Quantifies titanium content after acid digestion by measuring atomic emission intensity at characteristic wavelengths in plasma. |
| Residual Solvent (THF, DMF) | Gas Chromatography | Separates and quantifies volatile organic solvents using capillary column and flame ionization detection. |
| Molecular Weight Distribution | Gel Permeation Chromatography | Determines Mn, Mw, and PDI by separating polymer chains by hydrodynamic volume in porous column with refractive index detection. |
| Carbonyl Index | Fourier Transform Infrared Spectroscopy | Calculates ratio of carbonyl absorption peak (1710 cm-1) to reference peak (1450 cm-1) to assess thermal/oxidative degradation. |
| Particulate Contamination | Light Obscuration | Counts and sizes suspended particles in solvent-dissolved sample by measuring reduction in light transmission through flow cell. |
