Atom transfer radical polymerization (ATRP) is a kind of useful method for the realization of living polymerization and syntheses of block copolymers.Polystyrene double-caped with bromine (MWD=1.18)
Br-PSt-Br
was synthesized by ATRP method using α
α′-dibromoxylene as initiator and CuBr/2
2′-bipyridine as catalyst and ligand at 110℃.Then using the Br-PSt-Br as difunctional macromolecular initiator
ATRP of p-nitrophenyl methacrylate (NPMA) was realized and ABA type block copolymers
PNPMA-b-PSt-b-PNPMA
were synthesized.After hydrolyzation and acidition
amphiphilic ABA type block copolymers of methyl methacrylic acid and styrene
