淀粉是最常见和最容易获得的天然聚合物之一，使其成为合成聚合物的潜在生物基替代品。这项研究表明，一种简单的季铵盐与尿素或二醇结合形成有效的改性剂，生产出具有良好机械性能的柔性塑料，与某些聚烯烃塑料相当。加工条件显示出显着影响的聚合物的结构，其具有相应的效果后，所得塑料的机械和物理性能。使用基于甘油的改性剂产生完全可持续和可生物降解的材料，其可以注塑成型。
Starch is one of the most common and easily obtained natural polymers, making it attractive as a potential bio-based alternative to synthetic polymers. This study shows that a simple quaternary ammonium salt combined with urea or glycols forms effective modifiers that produce flexible plastics with good mechanical properties that are comparable to some polyolefin plastics. The processing conditions are shown to significantly affect the structure of the polymer which has a concomitant effect upon the mechanical and physical properties of the resulting plastic. Using a glycerol based modifier results in a totally sustainable and biodegradable material which can be injection moulded.
