Quality Control

Our production of this polymer intermediate adheres to stringent quality control protocols to ensure batch-to-batch consistency and performance reliability for your polymerization processes. Quality is verified through analytical methods including Gel Permeation Chromatography (GPC) for molecular weight distribution, Differential Scanning Calorimetry (DSC) for thermal properties, and FT-IR for structural confirmation. A comprehensive Certificate of Analysis (COA) detailing purity, intrinsic viscosity, and acid value is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect polymerization performance. Keep away from incompatible materials such as strong oxidizing agents.
