摘要

正

Amphiphilic star-block copolymers composed of polystyrene and poly（acrylic acid）were synthesized by iodide- mediated radical polymerization.Firstly

free radical polymerization of styrene was carried out with AIBN as initiator and 1

1-trimethyolpropane tri（2-iodoisobutyrate）as chain transfer agent

giving iodine atom ended star-shaped polystyrene with three arm chains

R（polystyrene）

.Secondly

tert-butyl acrylate was polymerization using polystyrene obtained as macro-chain transfer agent

and star-block copolymer

R（polystyrene-b-poly（tert-butyl acrylate））

with controlled molecular weight was obtained.Finally

amphiphilic star-block copolymer

R（polystyrene-b-poly（acrylic acid））

was obtained by hydrolysis of R（polystyrene-b-poly（tert-butyl acrylate））

under acidic condition.
