Several hindrances to the recycling of synthetic polymers, including material separation and post-treatment degradation of the macromolecular polymer chains, negatively affect the cost-efficiency and ...

Smashing compounds together to get them to polymerize sounds more like desperation than effective organic chemistry. But chemists Timothy M. Swager of Massachusetts Institute of Technology and Jens B.

A new method allows chemists to precisely place single monomers at any position within a polymer chain made of other types of monomers. With this single monomer, chemists can add various types of ...

Most polymers consist of long molecular chains made up of many units connected by covalent bonds — but supramolecular polymers are different. The strikingly dynamic properties of these materials arise ...

Starting with billions of molecules of monomer in a reactor, heat and pressure are applied in the presence of catalysts, causing one of the monomer double bonds to rearrange into two "half-bonds," one ...

Precise control over the location of monomers in a polymer chain has been described as the ‘Holy Grail’ of polymer synthesis. Controlled chain growth polymerization techniques have brought this goal ...

Researchers took a middling monomer and, by using a special catalyst, they created a tougher polymer that can form long chains. The polymer can then be easily depolymerized back to the monomer state ...

A new study provides an unprecedented look at how monomer sequence affects charge transport in precisely defined chain molecules. Researchers in the Schroeder and Moore groups at the University of ...

Controlling the molecular structure of amorphous cross-linked polymeric materials is a longstanding challenge. Herein, we disclose a general strategy for precise tuning of loop defects in covalent ...

Trinseo’s portfolio of STYRON™ Polystyrene resins, MAGNUM™ ABS resins, and TYRIL™ SAN resins can be manufactured with chemically recycled SM 1 produced according to the mass balance principle. This ...
