WebA new technique for recycling waste polycarbonate into a high-value polymer widely used in specialist engineering and medical applications has been discovered by researchers in California. The reaction uses a one-pot synthesis in which the polycarbonates are first depolymerised and then condensed to make poly (aryl ether sulfones) (PSUs). WebSep 27, 2024 · Other recycling methods continually shorten the polymer chain and change the final mechanical properties of the recycled material, which means there’s a limit to the number of times it can be recycled. Development of process improvements at APK’s R&D lab. Solvent-based polymer recycling has many advantages over chemical or mechanical …
