● Polymerization of styrene and acrylonitrile :

Due to the bifunctionality and the more constant reaction rate using this initiator, 

the resulting polymer has a higher molecular weight and shows reduced dispersity.

● Polymerization of acrylates and methacrylates:

Used as initiator for the solution, bulk and suspension (co)polymerization of 

acrylates and methacrylates.

● Used for the (co)polymerization of acrylonitrile
