Abstract
The work presents the synthesis and characterization of a biowaste-based tackifying phenolic resin and its application in rubber. Biophenol–furfural resin was successfully synthesized from monosaccharides and their derivatives prepared from naturally occurring Moringa oleifera gum. Different resins synthesized by varying the biophenol to monosaccharide ratio exhibited the glass transition temperature in the range of 16–31 °C. Characterization of the resin was done by Fourier transform infrared spectroscopy, 1H NMR, thermogravimetric analysis, and differential scanning calorimetry. The molecular weight of the resins was in the range of 652–1291 m/z. The effect of the synthesized resin on the mechanical, dynamic mechanical, tack, and rheological properties of the styrene butadiene rubber (SBR) was investigated. Synthesized resin improved the tack and the rheological properties of the rubber. Tensile strength of the SBR compound with resin having 2:1 biophenol to carbohydrate ratio was the same as or higher ...
