In this study, we propose an approach to the synthesis of new biodegradable polymer materials based on renewable raw feedstock (betulin) and derivatives of hydroxycarboxylic acids using a catalyst/catalytic system (γ-AlO, γ-AlO/TBHP) that is safe for health and the environment. The resulting polymers are linear thermoplastic polymers that undergo collapse upon melting in the presence of atmospheric oxygen. Moreover, these polymers demonstrate non-toxicity towards a range of Gram-positive and Gram-negative bacteria. The polycondensation of betulin with butyl lactate is particularly noteworthy.
在本研究中，我们提出了一种基于可再生原料（桦木醇）和羟基羧酸衍生物合成新型可生物降解聚合物材料的方法，使用对健康和环境安全的催化剂/催化体系（γ - AlO、γ - AlO/TBHP）。所得聚合物为线性热塑性聚合物，在大气氧存在下熔融时会发生塌陷。此外，这些聚合物对一系列革兰氏阳性菌和革兰氏阴性菌均表现出无毒性。桦木醇与乳酸丁酯的缩聚反应尤其值得关注。
