摘要：

We report a facile method for the synthesis of multi-block copolymers consisting of poly(ethylene glycol) (PEG) and poly(ester-amide) segments with an ordered side group sequence via multicomponent polymerization based on the Passerini reaction (PR). The technique involves the polymer supported liquid-phase synthesis of three PEG diacid macromonomers (M1-M3) via stepwise PR with tert-butyl isocyanoacetate and a functional aldehyde followed by selective hydrolysis, and the final multicomponent polymerization of M1-M3 with phenylacetaldehyde and 1,6-diisocyanohexane.
