A process allowing the synthesis of high molecular weight polyamides made from the above mentioned monomers is also described. Finally, compositions and articles including the same polyamides are also disclosed.
专利号:US-11926605-B2 优先权日:2018-03-21 标 题 :Functionalized bifuran and synthesis thereof 发明人:KANDEL KAPIL; COHN STEPHEN T; SALCICCIOLI MICHAEL; ATIENZA CRISITA CARMEN H; GALUSKA ALAN A 权利人:EXXONMOBIL CHEMICAL PATENTS INC 摘要:A 5,5′-Di-(protected)-2,2′-bifuran:wherein each R1 is independently an unsubstituted or substituted 5- or 6-member 1,3-dioxo-2-yl ring radical. Processes for making the bifuran include coupling 2-(protected)-furfural. Processes for using the bifuran include deprotection, functionalization, and/or polymerization to form a polyester. The polyester can be a renewable, high-performing polyester offering a combination of low cost of production, high sustainability, and excellent performance.
