Following the environmental problems caused by non-degradable plastics there is a need to synthesise greener and more sustainable polymers. In this work we describe, for the first time, the facile enzyme-catalysed synthesis of linear polyesters using dimethyl malonate as the diester. These polymers, containing a different aliphatic diol component (C, C or C), were synthesised in solventless conditions using immobilized lipase B as the biocatalyst. The potential of enzymes for catalysing this reaction is compared with the unsuccessful antimony- and titanium-catalysed synthesis ( > 150 °C). The application of the synthesized polymers as effective metal chelators in biphasic, green solvent systems was also described, together with the characterisation of the synthesised materials.
鉴于不可降解塑料引发的环境问题，有必要合成更绿色、更可持续的聚合物。在这项工作中，我们首次描述了使用丙二酸二甲酯作为二酯，通过简便的酶催化合成线性聚酯。这些聚合物含有不同的脂肪族二醇成分（C、C或C），在无溶剂条件下使用固定化脂肪酶B作为生物催化剂进行合成。将酶催化此反应的潜力与不成功的锑催化和钛催化合成（>150°C）进行了比较。还描述了合成聚合物在双相绿色溶剂体系中作为有效金属螯合剂的应用，以及合成材料的表征。
