Abstract

Reversible addition-fragmentation chain transfer (RAFT) polymerization has been used to prepare amphiphilic silicone-based copolymer via copolymerization of 2-hydroxyethyl methacrylate (HEMA) at the end of activated polydimethylsiloxane (PDMS). PHEMA-b-PDMS-b-PHEMA copolymer synthesized using direct polymerization of PDMS-macro CTA (macro chain transfer agent) and HEMA monomer in the presence of AIBN as an initiator. After completion of reaction, the prepared copolymer was successfully purified. The chemical structure characterization was assessed by FTIR spectroscopy. According to the FTIR results, the appearance of new broad peak in the region of 3200–3700 cm−1 was attributed to the hydroxyl groups. Also presence of high-intensity sharp peak at 1743 cm−1 related to the carbonyl functionalities and PDMS finger print peaks in the product spectrum, showed that copolymerization reaction was successfully performed.
