Synthesis of Poly(vinylbenzyl chloride) (PVBC) and Temperature Effect
Abstract
One of the versatile radical polymerization techniques, the reversible addition fragmentation chain transfer (RAFT) process, was used to synthesize the bifunctional monomer, vinylbenzyl chloride (VBC) into poly(vinylbenzyl chloride) (PVBC). The RAFT polymerization technique is widely used because of the commercially available RAFT agents in the country. The right choice of the RAFT agent will result in a good polymerization. Temperature of 60°C, 70°C and 80°C were chosen in this research study. The other conditions such as the purging and reaction time, the ratio of monomer/initiator for the control of VBC polymerization were kept constant for all reactions. The reactions were monitored by 1H nuclear magnetic resonance spectroscopy (NMR) in the presence of chloroform as the internal standard and also Fourier Transform infrared (FTIR). The characterizations using those two instruments were further discussed in the discussion part. The highest monomer conversion was 69% at 80°C for 22 hours.
