Polypropylene (PP) is one of the most widely used plastics in the world. By controlling the spatial orientation of the propylene building blocks and additional polar components, it should be possible to create a new generation of attractive, engineered, specialty plastics, with improved wettability or enhanced degradability, based on PP. In the journal Angewandte Chemie, Japanese scientists have introduced the basis for a new class of palladium catalysts for such polymerizations.
