Tetraoctylammonium Bromide

The anionic polymerization of oxetane in toluene was achieved using a combination of tetraoctylammonium bromide and simple triisobutylaluminum. By its copolymerization with ethylene oxide, di- and triblock copolymers were prepared in one and two steps respectively.

Abstract In summary, one can say that the versatility of living polymerization makes it a very useful and unique technique. Synthetic polymer chemists can utilize the lithium at the end of the chain to add polymer-like conjugated monomers, in order to tailor-make the polymer chain, or they can use chelating diamines to change the microstructure of the polymer chain. They can also run hydrogenation on anionically prepared polydienes to produce thermoplastic elastomers. They can transform anionically made polymer chain ends by adding ethylene oxide, carbon dioxide and halogens. This paper has emphasized recent advances in this field.
