Abstract

A new acrylamide monomer N-(3-(hexylamino)-N-(3-(isopropylamino)-3-oxopropyl) acrylamide (HA-NIPAM-AM) and a new RAFT agent O-propionyl-2-(N,N-diphenylcarbamothioylthio) propanoate have successfully been synthesized and used for the synthesis of poly(HA-NIPAM-AM) homopolymers via RAFT polymerization. The formed homopolymers have been characterized by GPC, ¹ H NMR, FTIR, contact angle measurement, TG-DTA, DSC, and PXRD. Numberaveragemolar masses of the prepared polymers are in the range of 2,500 – 11,500 g/mol. Selfassembly of homopolymer has been studied viacmc determination in water using pyrene as fluorescence probe, HRTEM and DLS. Polymeris thermally stable up to 300 °C and has a glass transition temperature at 85.3 °C. XRD study reveals the presence of nanophases in the polymer matrix. DFT calculation has revealed a helical backbone structure with the pendant groups exposed to inwards and outwards, respectively.
