Biobased polymers with excellent thermostability, mechanical properties, and optical transparency are desired in many demanding areas. In this study, a highly rigid tetravinyl compound (4V) was synthesized starting from citric acid. 4V further subjected to permethylation reaction, affording another (4MV) improved rigidity thermostability. Two series of networks were developed through the solvent-free thiol-ene coupling (or 4MV) three multifunctional thiol monomers. The exhibited similar glass transition temperature (Tg) values as compared based on 2,2′-diallyl bisphenol A, highlighting prominent 4V. 4MV higher Tg values, properties analogues same thiol. Highly transparent colorless films approximately 90% transmittance visible region (>500 nm) obtained for all polymers. These materials demonstrated moderate refractive indices (n) within range 1.5075–1.5779, along remarkably high Abbe numbers (νD) ranging 101 235. As result, these hold great potential various applications such encapsulation resins light-emitting diodes, antireflective coatings, display devices. This research paves way development biorenewable including Tg, transparency, robustness, balanced n νD values.
