Abstract

Sustainably producing plastic precursors that lead to performance properties in a variety of material chemistries is a major challenge—especially considering that most performance materials use aromatic structures that are still difficult to source sustainably. Here, we demonstrate catalyst-free, melt polymerization of dimethyl glyoxylate xylose (DMGX), a stabilized-carbohydrate that can be synthesized from agricultural waste with 97 % atom efficiency, into amorphous polyamides with semi-aromatic performance. Despite the presence of a carbohydrate core, these materials retained their thermomechanical properties through multiple rounds of high-shear mechanical recycling and could be chemically recycled. Technoeconomic and life cycle analyses suggested selling prices comparable to those of nylon 66 with a reduction of global warming potential of up to 75 %. This work illustrates the versatility of a stabilized-carbohydrate monomer to impart semi-aromatic performance in both degradable polyesters and highly durable engineering polyamides.
