By the experiment, the optimal technological conditions that the water and oil repellent finishing agent EX-910E is applied in polyester nonwovens were confirmed. The technological conditions include that EX-910E usage is 40g/l, the bridging agent F-2921E usage is 6g/l, the pre-curing condition is 100 × 2/3min, and the curing condition is 160 × 2.5 min. The results of the experiment indicated t...

A series of sugar-derived triols and biobased diacids were combined to prepare fully branched polyesters with different structural features by melt polycondensation.

The synthesis of polymers with tailored reactive functionalities plays an important role in the development of various materials for industrial and biomedical applications. In addition, there is a need to develop chemistry that is based on the use of biodegradable and renewable resources.1 Appreciable amounts of natural polyesters occur in higher plants as structural components, for example, cu...

The Front Cover shows the material flows in a circular plastics economy and highlights important role of catalysts its future implementation. For this purpose, we present zinc-based catalyst with newly developed hybrid guanidine ligand. In production renewable polyesters our is highly active towards ring-opening polymerization lactide at various reaction conditions, outperforming industrially u...

We report the alternating ring-opening copolymerization of dihydrocoumarin with epoxides catalyzed by chromium(III) salen complexes. This process provides access to a range of perfectly alternating polyesters with high molecular weights and narrow molecular weight distributions. Atactic poly(cyclohexene dihydrocoumarate) and poly(cyclopentene dihydrocoumarate) were found to be semi-crystalline ...
