Chemists have succeeded in specifically controlling the setup of precision polymers by light-induced chemical reactions. The new method allows for the precise, planned arrangement of the chain links, ...

Polymers are also called macromolecules, being very large organic molecules composed of an extremely high number of repeating smaller units called monomers. Their applications are widespread, and ...

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 ...

Yttrium-based catalysts can be used to stitch together two different lactone monomers in an alternating fashion to produce polyesters with well-defined primary structures. The ability to control the ...

Controlled radical polymerization is a means of manufacturing highly branched three-dimensional macromolecules known as hyperbranched polymers. It might employ inimers, compounds containing an ...

This illustration shows the C1 polymer formation, where the Pd-catalyst (red spere) is linearly combining a number of diazoacetate monomers (transparent sphere) to form the polymer main chain. For ...

Speaking in a Division of Polymer Chemistry session Tuesday, Coates noted that the polyacetal polymer is stable up to 325 °C. However, once researchers combine this plastic with a strong acid catalyst ...
