Manufacturing Quality Control of Poly(1,4-butanediol) bis(4-aminobenzoate)
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection / Colorimetry | Observe the color, state (powder or granules), and whether the sample is clumped; use a colorimeter for quantitative color assessment if necessary. |
| Molecular Weight and Distribution | Gel Permeation Chromatography (GPC) | Dissolve the sample in solvents such as tetrahydrofuran (THF) and use GPC to determine number-average molecular weight (Mn), weight-average molecular weight (Mw), and polydispersity index (PDI), evaluating the distribution of polymer chain lengths. |
| Melting Point and Thermal Properties | Differential Scanning Calorimetry (DSC) | Determine the melting temperature (Tm), glass transition temperature (Tg), and crystallization behavior, assessing thermal stability and processability. |
| Thermal Stability | Thermogravimetric Analysis (TGA) | Heat the sample under nitrogen or air atmosphere and record the mass loss process to determine the onset decomposition temperature (Td onset) and the maximum rate of weight loss temperature, evaluating the thermal degradation characteristics of the material. |
| Functional Group Structure Confirmation | Fourier Transform Infrared Spectroscopy (FTIR) | Confirm the presence of amino benzoate structural units by analyzing characteristic absorption peaks (e.g., N-H, C=O, C-O-C, aromatic ring vibrations). |
| Chemical Composition and Purity | Nuclear Magnetic Resonance Spectroscopy (¹H NMR or ¹³C NMR) | Dissolve the sample in deuterated solvents (e.g., DMSO-d6) and analyze monomer ratios, end-group structures, and impurity content through chemical shifts and integration areas. |
| Moisture Content | Karl Fischer Titration | Quantitatively determine the moisture content using the iodine-sulfur dioxide reaction, ensuring the raw material's dryness meets processing requirements. |
| Residual Monomers and Solvents | Gas Chromatography-Mass Spectrometry (GC-MS) | Detect residual monomers such as 1,4-butanediol, 4-aminobenzoic acid, catalysts, or organic solvents used during synthesis. |
| Acid Value / Amine Value | Titration Method (Acid-Base Titration) | Determine the terminal carboxyl groups (acid value) or terminal amine groups (amine value) through acid-base titration, reflecting the degree of polymerization and functional group end-capping status. |
| Solubility | Solubility Test | Add the sample to solvents of different polarities (e.g., DMF, DMSO, THF, chloroform), observe the dissolution speed and clarity, and evaluate process applicability. |
