What is the role of tetrabutylammonium chloride (TBACl) in the copolymerization process?

Label:chem

Topic
Tetrabutylammonium chloride (TBACl) is used as an initiator in the anionic ring-opening copolymerization (ROCOP) of epoxides with anhydrides.
Answer
TBACl initiates the polymerization by generating an anionic species that can ring-open the epoxide and anhydride monomers. It is crucial for the successful ROCOP of EO and anhydrides, as the reaction does not proceed without it.
