Could be a promising approach to better plastic recycling!
Alert: Plastophobia is a serious disease. Please seek immediate medical attention! (Caution: satire)
"... Separation takes work, but recycled mixed plastic is weak and often unsuitable for reuse. To get the plastics to mix better, scientists ... incorporated cross-linker molecules as part of the recycling process ... The result is stronger recycled plastic from common polymers, including low-density polyethylene and high-density polyethylene. When combined for recycling, different types of plastic tend to form blobs instead of mixing smoothly ... But adding 5% by weight of bis(diazirine)-based cross-linkers evens out the blobs. ..."
Crosslinkers force mixed plastics to blend Method makes stronger plastics, might mean easier recycling
Dynamic crosslinking compatibilizes immiscible mixed plastics (no public access)
