Dicumene Physical Properties

Jun 14, 2018

As the application of Dicumene co-batch becomes more and more widely used, the performance of the co-blow, such as its toughness, fire retardant, strength, ease of processing, etc., is required to be higher when it is used, and the appropriate one is selected when performing the operation. Additives to improve the performance of its combination of dry to a certain extent is a common and effective way.


It is a common and effective way to improve the performance of the polymer to a certain extent by properly selecting its additives during the operation process. In many of the polymer additives, dry-cut is a relatively new additive. It can be used as a synergistic synergistic agent for fire-retardant polymer flame-retardant, cross-linking, graft copolymerization, and physical properties of the polymer can be improved by cross-linking or graft copolymerization.


To some extent, the Dicumene is due to its special structure. To a certain extent, the C-C bond between the corresponding quaternary carbon atoms is not as stable as the general C-C bond. When exposed to heat or light, the free radicals form a radical, C•CH3CH3, which is stable due to the resonance of the benzene ring and the hyperconjugation effect of the methyl group. This confirms that the dry decomposition of cumene first forms cumene radicals. Cumene and α-methylstyrene are produced.


The full name of the Dicumene is known as -diphenylbutane or -dimethyl-2, to some extent due to its structural specificity, the CC bonds between its corresponding quaternary carbon atoms when used. The stability is not high, and it is easy to dissociate and form free radicals during the operation. In foreign countries, the double cumyl group and its derivatives are attributed to free radical initiators with unstable CC bonds. When used, its main role is to be fire-retardant. Synergists and cross-linking copolymerization catalysts.


In the process of operation, the Dicumene radical initiators such as azo compounds, peroxides, and the like are generally highly stable, and they are very safe during use, and they are used as a flame-retardant additive during operation. The agent, on the one hand, causes the transfer of the halogen chains by free radical formation. On the other hand, when the outside temperature rises, halogen radicals are generated to achieve a flame retardant effect.
