Star polymers with branched molecules containing multiple arms connected at a central core have properties different than their linear analogues. Herein, the linear block copolymers as the precursors of stars arms were synthesized by feeding reducing agent in activators regenerated by electron transfer atom transfer radical polymerization (ARGET ATRP). Several poly(butyl acrylate)-b-poly(tert-butyl acrylate) diblock copolymer with different DP and different block order were crosslinked with divinylbenzene, using arm first technique. Optimization of ARGET ATRP conditions allowed for the preparation of well-defined star polymers in high yield (> 95%). After hydrolysis, the PtBA segments were converted into poly(acrylic acid) and used as dopant for conducting polyaniline(PANI). The star copolymers composites with PANI resulted in flexible and stretchable electronic materials, which could be suitable for potential use as flexible electronic devices and energy storage. Scheme for synthetic route and GPC traces of star polymer as show in .
