摘要：

A block copolymer having polyisobutylene (PIB) as hydrophobic segment and poly(ethylene glycol) (PEG) as hydrophilic segments has been synthesized by a two-step process. Polyisobutylene was functionalized with phenol at both ends using BF3 . OEt(2) as catalyst, and then coupled with tosylated monomethoxy PEG. The reaction conditions were established by model studies. The characterization of the reaction product by NMR and GPC verified the formation of block copolymer by the coupling reaction.
