Mechanical recycling of postconsumer plastics, especially incompatible mixed plastics, is often a downcycling process, resulting in brittle materials. Here we introduce a multi-arm universal dynamic crosslinker (UDC) platform to enable mechanical upcycling of incompatible mixed plastics. The topological UDC platform is based on readily accessible diazomalonate carbene precursors joined by dynamic siloxane linkages. It creates in situ star-like multiblock copolymer compatibilizing architectures from mixed plastics, irrespective …
