Description

p-Divinylbenzene is a high-purity, bifunctional aromatic monomer essential for creating advanced cross-linked polymer networks. Its primary commercial value lies in its ability to act as a cross-linking agent, imparting enhanced thermal stability, mechanical strength, and chemical resistance to the final polymeric material. This compound is critically needed by manufacturers in the specialty polymer, ion-exchange resin, and advanced chromatography sectors for producing high-performance materials.

Application

• Primary cross-linking agent in the production of styrene-divinylbenzene copolymers for ion-exchange resins.
• Key monomer for manufacturing macroporous adsorbents and chromatography media used in pharmaceutical purification.
• Essential component in the synthesis of polymeric supports for catalysts and reagents in organic synthesis.
• Used in the production of gel permeation chromatography (GPC) standards for molecular weight determination.
• Cross-linker for specialty casting resins and composites requiring high thermal and dimensional stability.
• Raw material for advanced membrane and water treatment polymer formulations.

Quality Control

Our p-Divinylbenzene is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and isomer content, to ensure it meets precise specifications for polymer-grade applications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its polymerizable nature and sensitivity to light and strong acids, keep away from heat, sparks, open flame, and incompatible materials. For long-term storage, consider under an inert atmosphere to inhibit premature polymerization.
