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.

Products Description of 4-AminophenolCAS#123-30-8Aminophenol is also known as hydroxyaniline and aminohydroxybenzene. There are three isomers, namely o-aminophenol, m-aminophenol and p-aminophenol (4-aminophenol). In 1874, Baeyer et al. first prepared p-aminophenol. Due to the different relative positions of the hydroxyl group and the amino group, the three are also different in terms of physical and chemical properties. This product is weakly alkaline, weakly acidic and strongly reducing. Because it has both amino and phenol groups, it has the common properties of both.
