For example, it is now possible to prepare high molecular weight polymers (molecular weight > 50,000), to control the stereo-structure (tacticity) of the C–C main chain, and to quantitatively ...

The recent progress of research on polymer reactions utilizing dynamic covalent exchanges of alkoxyamine units—adducts of styryl and stable nitroxide radicals—is reviewed. The alkoxyamine ...

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 ...

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 ...

"For example, the nanosheets can be used in designing better batteries, ... Citation: Fluid mixing enables scalable manufacturing of soft polymer structures (2023 ...

Instead of linear polymer strands, Cai's structure resembles a bottlebrush -- many flexible side chains radiating out from a central backbone. Critically, the backbone can collapse and expand like ...

For instance, a branched polymer and a linear (unbranched) polymer of the same MW will exhibit different intrinsic viscosities. In addition, when the polymer changes structure across its MW ...
