Polisztiroldivinilbenzén

Polisztiroldivinilbenzén, often abbreviated as PSDVB or simply referred to as divinylbenzene copolymer, is a synthetic polymer that is a cross-linked copolymer of styrene and divinylbenzene. The ratio of styrene to divinylbenzene can vary, influencing the degree of cross-linking in the final material. Divinylbenzene acts as a cross-linking agent, connecting individual polystyrene chains and forming a rigid, three-dimensional network structure. This cross-linking is responsible for the insolubility and high thermal stability of PSDVB.

PSDVB is primarily used as a matrix material in various applications due to its inertness and mechanical strength. Its most common application is in the production of ion-exchange resins. The porous structure of PSDVB allows for the diffusion of ions, and when functionalized with charged groups, it can selectively bind and release target ions from solutions. These resins are widely used in water purification, chromatography, and chemical synthesis. Another significant use is as a support material in solid-phase peptide synthesis and other solid-phase organic reactions, where the insoluble polymer beads provide a stable scaffold for chemical transformations. Its resistance to solvents and heat makes it suitable for demanding chemical environments.
