Description

Poly(4-Vinylpyridine-Co-Ethylvinylbenzene), Cross-Linked is a high-performance, functionalized polymer resin designed for demanding separation and catalysis applications. Its unique structure, featuring pyridine and aromatic moieties within a robust, cross-linked matrix, provides exceptional chemical stability and tailored selectivity. This material is essential for industries requiring advanced purification, metal recovery, or specialized heterogeneous catalysis, offering a reliable and efficient solution for complex chemical processes.

Application

• Ion Exchange & Chelation: Selective removal and recovery of heavy metal ions (e.g., Cu²⁺, Ni²⁺, Pd²⁺) from industrial wastewater, electroplating baths, and mining leachates.
• Catalyst Support & Ligand: Serving as a solid support for immobilizing transition metal catalysts (e.g., for hydrogenation, cross-coupling reactions) or acting as a polymeric ligand itself.
• Chromatography & Purification: Used in preparative and process chromatography for the separation of pharmaceuticals, natural products, and fine chemicals based on ionic or affinity interactions.
• Acid Scavenging & Binding: Effective scavenger of acids (HCl, HBr) and other by-products in multi-step organic synthesis and combinatorial chemistry.
• Polymer-Supported Reagents: Base for creating custom polymeric reagents for use in automated synthesis, high-throughput screening, and flow chemistry systems.
• Analytical Sample Preparation: Solid-phase extraction (SPE) sorbent for the pre-concentration and clean-up of analytes prior to HPLC, GC, or ICP-MS analysis.
