Efficient synthesis of diallyl esters of the furan series from fructose and preparation of copolymers on their basis

Resumo

New unsaturated derivatives of the furan series, diallyl esters of furan-2,5-dicarboxylic acid and 5,5′-[oxybis(methylene)]di(2-furoic acid), which can be used as monomers and cross linking agents, were synthesized by the aerobic oxidation of 5-hydroxymethylfurfural and 5,5′-oxybis(5-methylene-2-furaldehyde) obtained by catalytic dehydration of fructose. Optimum conditions for the synthesis of the above-mentioned compounds and their copolymerization with butyl methacrylate were determined. Varying the amount of the cross-linking agent, the thermal stability, adhesion, strength and optical properties of copolymers can be controlled. New cross-linking agents obtained from renewable resources can be considered as an alternative to the important cross-linking agent, diallyl phthalate, produced from petroleum.
