Styrene divinylbenzene-manufacture,factory,supplier from China

Products Description of Divinylbenzene CAS#1321-74-0Divinylbenzene is a very useful crosslinking agent, widely used in ion exchange resins, ion exchange membranes, ABS resins, polystyrene resins, unsaturated polyester resins, synthetic rubber and other fields. However, divinylbenzene is highly reactive. During the distillation process, it is very easy to undergo free radical polymerization due to the initiation of metal ions and heat. The higher the temperature, the faster the polymerization rate.
