the formation of terpene-derived polyesters. Three methods for the synthesis of the novel hydroxy-acid 6 are reported and their green-credentials scrutinised through comparison of their sustainability-metrics. Step-growth homo-polymerisation of 6 is demonstrated to yield a low molecular weight (2.6 kDa) novel polyester with 100% of its carbon content originating from the terpene starting material. The
柠檬烯的官能化使得能够合成两种可再生来源的单体,以形成萜烯衍生的聚酯。报告了三种合成新型羟基酸6的方法,并通过比较其可持续性指标来审查其绿色证书。已证明6的逐步增长均聚反应可制得低分子量(2.6 kDa)新型聚酯,其碳含量的100%来自萜烯原料。已显示出相应的二醇2与可再生的二酸起共聚单体的作用。所得聚酯显示出令人印象深刻的M n s,T g高达30 kDa介于-6和24°C之间。已经表明这些材料在用于二醇单体2的回收的碱性条件下解聚。
