Description

Application

N,N,N′,N′′,N′′ Pentamethyldiethylenetriamine can be used as:

• An organocatalyst in ring-opening polymerization (ROP) of trimethylene carbonate. This catalyst can be easily removed after the reaction compared to metal catalysts.
• A catalyst along with CuBr to synthesize a series of side-chain azobenzene poly(meth)acrylates via the atom transfer radical polymerization(ATRP) technique.
• An initiator to grow polystyrene chains to prepare polyolefin-polystyrene copolymers.
