Dendritic-linear polyether block polystyrene was synthesized via atom transfer radical polymerization(ATRP)that the dendritic polyether having the core of —CH
2
Br
copper(I) bromide and 2
2'-biphenyl as the initiator
catalyst and ligand respectively. Element Analysis instrument was used to analysis the content of carbon and hydrogen belonged to the dendritic polyether initiators. IR Spectra and HNMR were chosen to characterize the structure of the dendritic-linear polymers. The results show that the component of the dendritic polyether form the first to the third generations are according with the perfect component; the dendritic-linear polymer initiated by the dendritic polyether have the clear structure
but the bromide at the end of polymer chains may be removed under the polymerized conditions.
