Typical Applications and Advantages of Dicumene Use With the wide application of polymers, stricter requirements have been presented for polymer properties, such as fire retardant, strength and process ability, in practical applications. Adding appropriate modifiers, such as dicumen, can improve the performance of the polymer. So, how does dicumene play a role in the polymer? With regard to the current application, in fact, it has already become a very common additive. It is mainly used as a synergistic synergist of fire retardant and flame retardant polymer. The cross linking and graft copolymerization of the catalysts can improve the mechanical properties of the polymers by cross linking or graft copolymerization. The reason for this performance is mainly due to the particularity of the structure of dicumene itself. In the case of heat or light, the product is easy to divide and form a certain free radical. The free radical is more stable due to the resonance of the benzene ring and the hyper-shock effect of methyl. In fact, the modification of Dicumene in the polymer is achieved through the free radical. It is found that when the temperature increases, the half-life of dicumen becomes shorter. The temperature of its decomposition is high. And at 230 degrees, the half-life will reach thirty minutes.
Usually used at a temperature of 200 degrees, dicumen is used primarily for the cross linking reaction or polymer grafting at higher temperatures. The application and the effect of the application are also different. At the same time, compared to general free radical initiators such as diazo, peroxide and azo compounds, dicumen is more stable and safer to use.
