AAAS Newcomb Cleveland Prize
2017 Award Recipients
The 2017 Newcomb Cleveland Prize was awarded to James M. Eagan, Jun Xu, Rocco Di Girolamo, Christopher M. Thurber, Christopher W. Macosko, Anne M. LaPointe, Frank S. Bates, Geoffrey W. Coates for their outstanding report "Combining polyethylene and polypropylene: Enhanced performance with PE/iPP multiblock polymers," published in Science 24 February 2017.
Polyethylene and isotactic polypropylene are the two largest use commodity plastics and thus also make up a large fraction of the waste stream. However, the two plastics won't mix together, thus decreasing the value and options available for dealing with mixed waste. Eagan et al. report the synthesis of multi-block copolymers of isotactic polypropylene and polyethylene using a selective polymer initiator. They show that the tailorable high molecular weight blocks can reinforce the interface between iPP and HDPE and serve as compatibilizers for blends of the two polymers. This project brought together chemists and engineers to make a significant conceptual (and practical) advance. The science of synthesizing multi-block copolymers is of fundamental value and there is remarkable potential for this method to be scaled up and to produce real societal impact.
