A brief description of the structural properties of dicumene Mar 23, 2018

Dicumene belongs to a new type of additive. This additive can be used as synergist synergistic agent for fire retardant and flame retardancy of polymers. Crosslinking and graft copolymerization of catalysts can improve physical properties of polymers through cross-linking or graft copolymerization.

 

In comparison, dicumene has a more specific structure: The C-C bond between the corresponding quaternary carbon atoms is less stable than that of the general C-C bond. When heated or illuminated, the free radical is formed easily. The free radical has the resonance of the benzene ring and the super conjugation effect of the methyl group, and is stable. Meanwhile, dicumene is more stable, and the use is safer than peroxide, azo compound and other general free radical initiators.

 

It is because of such a special structure that, as a kind of additive, it can effectively improve the physical properties of the polymer. For example, when used as a flame retardant synergist, on one hand, it can transfer halogen chains by forming free radicals. On other hand, when the external temperature rises, the halogen free radical is generated to achieve the effect of flame retardance.

 

In a word, in the polymer, dicumene can be used as a polymer fire retardant synergist, which is safer.
