A general strategy for heterogenizing olefin polymerization catalysts and the synthesis of polyolefins and composites [PDF]
Nature Communications, 2022 The heterogenization of homogeneous metal complexes on solid supports has a series of drawbacks that restrict their implementation in olefin polymerization, particularly for copolymerization with polar comonomers. Here the authors show an ionic anchoring
