Polyolefins

Scientists at the Institute for Cooperative Upcycling of Plastics (iCOUP), an Energy Frontier Research Center led by Ames Laboratory, have discovered a chemical process that provides biodegradable, valuable chemicals, which are used as surfactants and detergents in a range of applications, from disc more

Plastic is ubiquitous in people's lives. Yet, when plastic-containing items have fulfilled their missions, only a small amount is recycled into new products, which are often of lower quality compared to the original material. And, transforming this waste into high-value chemicals requires substantia more

While plastics recycling is not new science, current processes don't make it economically worthwhile-- waste plastics get "down-cycled" into lower grade, less useful material. It's a challenge that continues to be an obstacle in tackling a growing global pollution crisis in single use plastics. A mu more

Fu-Rong Zeng, Qi-Lin Zhu, Zi-Long Li Post-polymerization modification of ADMET polyketone was conducted in a sequential manner via oxime chemistry and electrophilic alkoxyetherification. Complete conversion of the reactive site was realized in both steps, and the two modification reactions showed more

Multiple synthetic strategies were perfomed in order to tether zirconium-based catalyst to the 2D and 3D molecular sieves for olefins polymerizations. The anchoring of fluorene silane to the mesoporous MCM-41 was performed in order to obtain a stable catalyst for olefin polymerization (1@MCM-41). Us more

ABSTRACT Bio‐based laminate composites, consisting of alternatively stacked poly(lactic acid) (PLA) sheet and randomly oriented areca fiber mat, were processed via film stacking technique (FST). FST was chosen as it is a commercially viable, low energy‐intensive process for fabricating fiber‐rei more
