SYNTHESIS OF A NOVEL SILICONE- AND TRIAZINE-BASED COPOLYMER WITH FURFURYL SIDE GROUPS

Abstract

S-triazine derivatives are known to have great potential in diversifying the structural design of polymer materials due to the stepwise reaction of cyanuric chloride, particularly in optoelectronic applications. In addition, the hydrogen bonds formed by the triazine ring are known to play an important role in molecular arrangement, providing triazine-based polymer materials with excellent mechanical properties. In the present work, a triazine-furan precursor will be combined with polydimethylsiloxane (PDMS) and polyoxypropylenediamine to create a novel polymer that bears furfuryl side groups. This polymer has great potential to be used for self-healing applications due to the reversibility of triazine π-π stacking and hydrogen bonding as well as the ability of the furfuryl group to form dynamic covalent bonds. Thin-layer chromatography (TLC) and gel permeation chromatography (GPC) was used to investigate the reaction conditions (GPC). The research of this reaction revealed that the best conditions for the synthesis of this copolymer were at a temperature of 110 oC for 24 hours and determined an average molecular weight (Mn) of around 19800 (g/mol). Fourier-transform infrared spectroscopy (FT-IR) and nuclear magnetic resonance (NMR) are used to determine the structure of the synthesized compounds. Besides that, from the 1H-NMR spectrum NMR was found that feeding molar of 21.32/1/19.50 for TF, PDMS, and Jeffamine, respectively.
