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 ...

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 ...

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 ...

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 ...

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 ...

Developing a practical polymer that can break down to its monomer and then be repolymerized over and over again has been a long-standing goal of plastics makers and recycling advocates. Such a ...

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 ...

In this paper, we describe the results of the π-allylnickel-catalyzed living dispersion polymerization of allene derivatives that enables the precision synthesis of well-defined polymer microspheres.
