A Note about Crosslinking Density in Imprinting Polymerization [PDF]
Molecules, 2021 Imprinting polymerization is an exciting technique since it leads to specific binding sites, which are the basis of a variety of applications, such as sensors, detectors, and catalysts. The specific binding sites are created using templates and then fixing the structure of the binding site with crosslinking.

Auxetic polymer networks: The role of crosslinking, density, and disorder
The Journal of Chemical Physics, 2023 Low-crosslinked polymer networks have recently been found to behave auxetically when subjected to small tensions, that is, their Poisson’s ratio ν becomes negative. In addition, for specific state points, numerical simulations revealed that diamond-like networks reach the limit of mechanical stability, exhibiting values of ν = −1, a condition that we ...

Comparison of Three NMR Methods for Measuring Crosslink Density of Rubbers
Chinese Journal of Magnetic Resonance, 2017 NMR is a frequently used technique for measuring crosslink density of rubbers. In this work, three commonly used proton NMR methods for measuring crosslink density of rubbers[i.e., 1H double-quantum (DQ) NMR, 1H Hahn echo and 1H CPMG echo] were compared.
