Abstract In this study a new oligomeric DOPO-containing compound with flame retardant properties was obtained based on polyethyleneimine (PEI). The oligomer was synthesized using the following components: polyethyleneimine, benzaldehyde, and 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO). The PEI-based flame retardant in an amount of 8% by weight was incorporated into the polymer matri…

Abstract Polyolefins are essential plastics to modern life yet create mounting sustainability challenges. Chemical recycling technologies are key but often require harsh conditions, costly hydrogen, noble metals, or complex catalysts with challenging design. We report hydrogen- and solvent-free depolymerization of polypropylene consumer goods at 240 °C, achieving >80% yield into gasoline hydro…

<div class="section abstract"> <div class="htmlview paragraph">Polyimides are a class of polymers with imide rings in their main chains. They are renowned for their exceptional mechanical properties, high-temperature resistance, low-temperature endurance, and resistance to chemical solvents, which allow for long-term use under harsh medical operating conditions. Consequently, research…

Published in Nature Communications, the study introduces a multiscale optimization framework that uses biopolymers to improve the printability, stability, and processing speed of natural earth materials. The researchers te…

Many plastic products are designed to be used only once, yet the material itself lasts for years. But a new strategy is addressing this problem by creating products that self-destruct on command, known as living plastics. These materials incorporate activatable, plastic-degrading microbes alongside the polymers. One team reporting in ACS Applied Polymer Materials used two […]
