A study was conducted to demonstrate facile synthesis of polymerization of acrylic acid (PAA) using reversible addition fragmentation chain transfer (RAFT) process, initiated through ultraviolet radiation in aqueous solution at high temperatures. It was observed that the RAFT process provided an added advantage of being environmental friendly solvent at higher temperatures, making it a highly valuable tool to conduct such studies. The method enabled acrylic acid to be polymerized in the presence of a trithiocarbonate CTA and TRITT agents at different ratios of monomer to CTA. The polymerization was performed without the addition of a photoinitiator. It was also observed that under ultraviolet radiation initiation, TRITT can be used to initiate and control the polymerization of acrylic acid to obtain well-defined linear PAA at room temperature.
