| Coatings | Provides excellent weather resistance and adhesion; serves as a film-forming agent | Acrylic (ester) copolymers are prepared via emulsion or solution polymerization, then blended with other components to formulate coating systems |
| Textile Treatment | Improves fabric hand feel, wrinkle resistance, and dyeability | Acrylic (ester) copolymers are applied as finishing agents onto textile surfaces using an impregnation-drying process |
| Construction | Serves as a base component in waterproofing agents, sealants, and other construction materials | Products with targeted performance are synthesized via controlled copolymerization under specific conditions, then processed into final forms such as liquids or pastes |
| Papermaking | Enhances paper strength, wet strength, and printability | Acrylic (ester) copolymers are added to the pulp slurry or applied via coating during later stages of paper production |
| Personal Care | Functions as a thickener, stabilizer, and similar additive in cosmetics and personal care products | Copolymerization is carried out with selected monomers, and molecular weight is adjusted to meet requirements of specific applications |
| Water Treatment | Acts as a flocculant to remove suspended solids from water | Copolymer charge characteristics and molecular structure are tailored to optimize performance in water treatment processes |
Manufacturing Quality Control of 25035-69-2
| Test Item | Common Test Method | Method Overview |
|---|---|---|
| Solid Content | Oven Drying Method (GB/T 1725) | The sample is dried to constant weight at a specified temperature (e.g., 105±2°C), and the solid content is calculated based on mass loss. Suitable for aqueous or solvent-based acrylic copolymer emulsions or solutions. |
| Average Molecular Weight and Molecular Weight Distribution | Gel Permeation Chromatography (GPC/SEC) | The sample is dissolved in an organic solvent (e.g., THF), separated by molecular weight through a chromatographic column, and analyzed using a calibration curve to determine number-average molecular weight (Mn), weight-average molecular weight (Mw), and polydispersity index (PDI). |
| Residual Acrylic Monomer | Gas Chromatography (GC) or High-Performance Liquid Chromatography (HPLC) | After appropriate pretreatment (e.g., extraction, dilution), residual unreacted acrylic or acrylate monomers are quantified using GC or HPLC to ensure compliance with safety standards (e.g., cosmetic regulations). |
| Acid Value (Saponification Value) | Titration Method (GB/T 6365) | The carboxylic acid groups in the sample are titrated with a standard alkaline solution (e.g., NaOH). The result is expressed as milligrams of KOH consumed per gram of sample, indicating the content of acidic groups, which affects pH and stability. |
| pH Value | pH Meter Method | The sample is prepared as an aqueous solution at a specified concentration and measured directly using a calibrated pH meter. Essential for assessing acidity/basicity and ensuring stability in applications such as cosmetics and coatings. |
| Viscosity | Rotational Viscometer Method (e.g., Brookfield) | Measures the resistance of the sample under a rotating spindle at a set speed and temperature, yielding dynamic viscosity in mPa·s. Used to control application properties and rheological behavior. |
| Transmittance / Turbidity | UV-Visible Spectrophotometry (UV-Vis) | The diluted sample is measured at a specific wavelength (e.g., 550 nm) to determine transmittance, evaluating the clarity of the polymer solution and reflecting emulsion stability or impurity levels. |
| Particle Size Distribution (for Emulsions) | Dynamic Light Scattering (DLS) | Laser light is directed at the emulsion particles; fluctuations in scattered light intensity are analyzed to calculate particle size distribution (Z-average diameter, PDI), used to assess emulsion stability and film-forming properties. |
| Thermal Stability | Thermogravimetric Analysis (TGA) | Measures sample mass change under programmed temperature conditions (e.g., 25–600°C) to analyze decomposition temperature and residue (char) content, evaluating the polymer’s heat resistance. |
| Heavy Metal Content | Atomic Absorption Spectroscopy (AAS) or Inductively Coupled Plasma Mass Spectrometry (ICP-MS) | After digestion, the sample is analyzed by AAS or ICP-MS to determine concentrations of heavy metals (e.g., Pb, Cd, Hg, As), ensuring compliance with regulatory requirements for cosmetics, food-contact materials (e.g., EU Regulation EC 1223/2009). |
| Total Free Monomers | LC-MS/MS (Liquid Chromatography-Tandem Mass Spectrometry) | High-sensitivity detection of trace unreacted monomers (e.g., methyl methacrylate, butyl acrylate), suitable for high-purity applications such as medical polymers or food packaging materials. |
| Saponification Value | Alkaline Hydrolysis-Titration Method | Ester groups are hydrolyzed under basic conditions, excess base is back-titrated with acid, and the KOH consumed per gram of sample is calculated. Reflects ester group content and helps control hydrophilic/lipophilic balance in copolymers. |
| Water Solubility / Dispersion Stability | Centrifugation or Standing Observation Method | The sample is centrifuged (e.g., 3000 rpm, 30 min) or left standing to observe phase separation or precipitation, evaluating its dispersion stability in water—important for water-based coatings and personal care formulations. |
| Infrared Spectroscopy (Structural Confirmation) | Fourier Transform Infrared Spectroscopy (FTIR) | Characteristic absorption peaks (e.g., C=O at 1730 cm⁻¹, C-O at 1150–1250 cm⁻¹) confirm the presence of acrylic ester structures, identifying target functional groups or potential contaminants. |
| Residual Solvents | Headspace Gas Chromatography (HS-GC) | For solvent-based products, headspace sampling is used to detect residual solvents such as ethanol, acetone, or toluene, ensuring compliance with standards like ICH Q3C or GB 31604.8. |
