For decades, the promise of plastic recycling has quietly foundered on a molecular reality: different polymers, like stubborn strangers, refuse to mix. Now, researchers led by Francis Starr and Max Hanrahan have used computer simulations to show that dynamic crosslinks — molecular bridges that form and dissolve repeatedly between polymer chains — can coax incompatible plastics into a more cooperative state, lowering the barriers of temperature and surface tension that have long made mixed-plastic recycling impractical. It is a reminder that some of our most persistent material problems may yie
