Polyolefins

The United Nations estimates that more than 8 million tons of plastics flow into the oceans each year. A new chemical conversion process could transform the world's polyolefin waste, a form of plastic, into useful products, such as clean fuels and other items. "Our strategy is to create a driving fo more

There's a good chance you've touched something made out of the polyolefin polymer today. It's often used in polyethylene products like plastic bags or polypropylene products like diapers. As useful as polyolefins are in society, they continue to multiply as trash in the environment. Scientists estim more

Inspired by proteins that can recognize dangerous microbes and debris, then engulf such material to get rid of it, polymer scientists led by Todd Emrick at the University of Massachusetts Amherst have developed new polymer-stabilized droplet carriers that can identify and encapsulate nanoparticles f 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
