摘要

这篇小型综述强调了绿色化学的许多原理可以用来使聚合物更具可持续性。近年来,可再生原料的使用急剧增长,包括使用生物衍生单体和天然聚合物(如碳水化合物)的改性。聚合物也被设计为允许进入循环经济,特别是在可以发生触发解聚(例如催化回收到单体)的地方,这可以使混合废物流中的其他塑料容易分离。计算研究和反应监测对于识别和理解聚合物合成和降解的反应性趋势是有用的。无溶剂反应,包括机械化学,可以用来减少过程质量强度和环境影响。应鼓励使用标准聚合物降解条件(例如ISO标准)和生命周期评估,特别是热点分析,以便加速这一重要领域的进展。

Applying the principles of green chemistry to achieve a more sustainable polymer life cycle

Applying the principles of green chemistry to achieve a more sustainable polymer life cycle
This mini-review highlights how many of the principles of green chemistry can be used to make polymers more sustainable. The use of renewable feedstocks has grown enormously in the recent years including the use of bio-derived monomers and modifications of natural polymers such as carbohydrates. Polymers are also being designed to allow entry into the circular economy especially where triggered depolymerization (e.g. catalytic recycling to monomer) can occur, which can allow easy separation from other plastics in a mixed waste stream. Computational studies and reaction monitoring are useful in identifying and understanding reactivity trends for polymer synthesis and degradation. Solvent-free reactions, including mechanochemistry, can be employed to reduce process mass intensity and environmental impacts. Use of standard polymer degradation conditions (e.g. ISO standards) and life-cycle assessments, in particular hot spot analyses, should be encouraged in order to accelerate progress in this important field.
