Collaborative CSP research by Coates, LaPointe, Bates, and Macosko groups has been published in Science. This research focuses on compatibilizing the recycling process for two of the most common plastics. Polyethylene (PE) and isotactic polypropylene (iPP) constitute nearly two-thirds of the world’s
plastic. Despite their similar hydrocarbon makeup, the polymers are immiscible with one another. Thus, common grades of PE and iPP do not adhere or blend, creating challenges for recycling these materials.We synthesized PE/iPP multiblock copolymers using an isoselective alkene polymerization initiator. These polymers can weld common grades of commercial PE and iPP together, depending on the molecular weights and architecture of the block copolymers. Interfacial compatibilization of phase-separated PE and iPP with tetrablock copolymers enables morphological control, transforming brittle materials into mechanically tough blends.

The Center for Sustainable Polymers is excited to partner with the Minnesota Corn Growers Association (MCGA) through research, education, and outreach efforts. Researchers in the Center for Sustainable Polymers are working to develop new monomers and polymers that expand the uses of corn-based sugars. Additionally, our education and outreach programs are working to reach rural Minnesota through developing new materials for 4-H Cloverbuds (grades K-2), and through our MCGA sponsored teacher workshop in green chemistry.
The CSP and MCGA have partnered to develop the Green & Sustainable Chemistry Workshop for High School Teachers. Learn more about the workshop here.

"Most polymers we use in everyday life are from petroleum-based products, and although they’re durable in use, they’re also durable in waste." —Director Marc Hillmyer
