In order to design sustainable materials from vegetable oil-based fatty acids, we propose herewith a method to obtain unsaturated dicarboxylic acids as a polymerizable monomer through metathesis reaction of oleic and linoleic acids with the 2nd generation Grubbs catalyst. Subsequently, functional green polyester was produced from dicarboxylic acids and aromatic diol. Dicarboxylic acid having similar structure i.e., octadec-9-enedioic acid was successfully obtained from metathesis of both oleic and linoleic acids. Condensation polymerization of octadec-9-enedioic acid with 1,6-hexanediol and 4,4′-biphenol was carried out and it was shown that polymer with aromatic backbone had higher glass-transition temperature than aliphatic polyester.
为了从植物油基脂肪酸中设计可持续材料,我们在此提出了一种通过油酸和亚油酸与第二代格鲁布斯催化剂进行复分解反应来获得不饱和二羧酸作为可聚合单体的方法。随后,由二羧酸和芳香族二醇生产出功能性绿色聚酯。通过油酸和亚油酸的复分解,成功地获得了具有相似结构的二羧酸,即十八-9-烯二酸。将十八烯二酸与1,6-己二醇和4,4'-联苯酚进行缩聚,结果表明,具有芳香族骨架的聚合物比脂肪族聚酯具有更高的玻璃化转变温度。
