Overview[edit]

Dicumyl peroxide is an organic compound with the formula (C_H_C(CH_)_O)_. It is a white crystalline solid that is used as a radical initiator in the polymerization of styrene, acrylics, and polyethylene.

Chemical Structure[edit]

Dicumyl peroxide is a peroxide, which means it contains a peroxide group (_O_O_) in its structure. The compound consists of two cumyl groups (C_H_C(CH_)_) connected by a peroxide linkage. This structure is responsible for its ability to decompose and generate free radicals, which are essential in initiating polymerization reactions.

Applications[edit]

Dicumyl peroxide is widely used in the plastics and rubber industries. It serves as a cross-linking agent for polyethylene and polypropylene, improving the mechanical properties and thermal stability of these materials. In the production of polystyrene, dicumyl peroxide acts as a catalyst to initiate the polymerization process.

Safety and Handling[edit]

As with many peroxides, dicumyl peroxide is a hazardous material and must be handled with care. It is a strong oxidizing agent and can pose a risk of explosion if not stored properly. Safety measures include storing it in a cool, dry place away from reducing agents and flammable materials.

Decomposition[edit]

Upon heating, dicumyl peroxide decomposes to form acetophenone and methane, along with free radicals. This decomposition is exothermic and is the basis for its use as a radical initiator. The decomposition temperature is a critical parameter in its application, as it determines the onset of radical generation.
