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, ...

Scientists have recently shown how valuable light-sensitive macromolecules are: when exposed to the right wavelength of light, they can be transformed so as to change, erase or decode the molecular ...

Very long linear macromolecules can occur as fluid polymers at temperatures above their point of crystallization. These are commonly referred to as polymer melts and are key ingredients in many modern ...

Polymer chemistry is central to the development of new technologies and substances. Materials based upon natural and synthetic organic macromolecules, polymers, and hybrid derivatives have enormous ...

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

A theoretical analysis of polymer behavior suggests that large molecules should behave very differently when they are in a vacuum than when in solution. The finding suggests that with better ...

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 ...

Marc A. Hillmyer, Presidential McKnight Endowed Chair and Professor of Chemistry at the University of Minnesota, has been named the new editor-in-chief Macromolecules. He will succeed Timothy P. Lodge ...

A polymer is a chemical compound that contains a large number of identical molecular repeating units. A plastic material is a polymer, typically modified with additives, which can be molded or shaped ...

Osaka, Japan – Often referred to as smart materials, temperature-responsive or thermoresponsive polymers are gaining attention for their ability to respond to external temperature changes, allowing ...
