Polyallene has some particular application due to its unique structure, but study on copolymer containing polyallene was limited because of its polymerization methods. We first prepared Azo-TEMPO (2,2,6,6-tetramethyl-1-piperidine-N-oxyl) bifunctional initiator. Next, PS-b-PPOA-b-PS [Polystyrene-b-poly (phenoxyallene)-b-polystyrene] was prepared by sequential radical polymerization of phenoxyallene (POA) and NMRP (nitroxide-mediated radical polymerization) of styrene. Polyallene-based copolymer was easily prepared by the mechanism transfer strategy, which greatly expands its application.

Key words: polyallene, block copolymer, bifunctional initiator
