Quality Control

Our Poly(4-Aminostyrene) is manufactured under controlled conditions to ensure batch-to-batch consistency. Quality is verified through a series of analytical tests, which may include determination of amine content, molecular weight distribution, and purity assessment. A Certificate of Analysis (COA) detailing specific results is provided with each shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store the material under an inert atmosphere for long-term preservation. Keep away from strong oxidizing agents.
