Abstract

original image

A new strategy for preparation of 3-miktoarm star terpolymer was suggested. The fully-defined precursors PtBA-N3 (poly(tert-butyl acrylate) with azide end group), TEMPO-PEO or TEMPO-PCL (poly(ethylene oxide) or poly(ε-caprolactone) with TEMPO end group) and PS-alkyne/Br (polystyrene with ω-propargyl and ω′-(2-bromoiso butyryl) groups) are designed and prepared first, then the star terpolymers composed of PtBA, PS, and PEO (PCL) arms could be obtained via combination of “click chemistry” and ATNRC reaction using a one-pot.
