Computational physicists and chemists have shed new light on how the polymer structure bears on the glass-transition temperature in the forming of glass in atactic polystyrene (PS), a commonly ...

Polymers with favorable physical properties can be created by altering their properties by derivatisation or changing their structure. For example, the bromination of polystyrene gives fire resistant ...

By attaching polystyrene chains to silica particles, researchers created "hairy particles" that self-assemble into a structure where the degree of entanglement can be controlled.

Nature Nanotechnology - Effect of supramolecular structure on polymer nanofibre elasticity. ... (Fig. 1a) and polystyrene nanofibres 6 (Fig. 1b) observed when their diameters became small enough.

Polymers are extensively used throughout industry, whether as naturally occurring materials like starch and cellulose, or synthetic commodities like nylon, polystyrene and polyethylene. Polymer ...

Now, researchers have overcome a major hurdle: getting bacteria to produce polymers that contain ring-like structures, which make the plastics more rigid and thermally stable.
