Synthesis, Structure, and Properties of Bio-based Triblock Elastomers Based on Guaiacol

Abstract
A series of poly (guaiacol acrylate)-block-poly(methyl acrylate)-block-poly (guaiacol acrylate) (PGA-PMA-PGA) triblock copolymer elastomers were successfully prepared via reversible addition-fragmentation chain transfer (RAFT) polymerization method using a lignin derivative guaiacol acrylate (GA) as hard segment monomer and methyl acrylate (MA) as soft segment monomer. Nuclear magnetic resonance (NMR), gel permeation chromatography (GPC), thermogravimetric analysis (TG), differential scanning calorimetry (DSC), mechanical tensile testing, small-angle X-ray scattering (SAXS), and UV-visible(UV-Vis) spectroscopy were used to analyze the compositions, molecular weight, thermal stability, glass transition temperature, mechanical properties, microphase separation structure, and UV shielding performance of the synthesized elastomers materials. The results showed that the thermal decomposition temperature of PGA-PMA-PGA was above 300 ℃, which met the requirements of most working environments, exhibiting excellent thermal stability. Their mechanical properties could be adjusted by controlling the hard segment content. These triblock elastomers had two glass transition temperatures corresponding to the PMA soft segment (17.3 ℃) and the PGA hard segments (80.3 ℃), respectively, providing the material with ductility and strength. When deformed, the PGA hard segments would be oriented along the stretching direction. Due to the introduction of guaiacol structural units with a large number of aromatic rings, these elastomer materials showed superior UV-absorption capabilities. -
