Raman spectroscopy is a characterization technique that detects bond vibrations that change the polarizability of the molecule. It is therefore a non-destructive technique and is suitable for examining both polymers and their additives. In general, Raman spectra can be used for identification purposes by referring to a collection …

But long and/or thin, they tangle and pulling them apart in solution/melt or across an interface is difficult, giving high viscosity and adhesion. The definition of entanglement is surprisingly simple: if the ...

Polymer physics is the field of physics that studies polymers, their fluctuations, mechanical properties, as well as the kinetics of reactions involving degradation and polymerisation of polymers and monomers respectively. While it focuses on the perspective of condensed matter physics, polymer physics is … See more Models of polymer chains are split into two types: "ideal" models, and "real" models. Ideal chain models assume that there are no interactions between chain monomers. This assumption is valid for certain polymeric … See more The statistics of a single polymer chain depends upon the solubility of the polymer in the solvent. For a solvent in which the polymer is very soluble (a "good" solvent), the chain is more … See more Whether a polymer is flexible or not depends on the scale of interest. For example, the persistence length of double-stranded DNA is about 50 nm. Looking at length scale smaller than 50 nm, it behaves more or less like a rigid rod. At length scale much … See more • File dynamics • Important publications in polymer physics. • Polymer characterization See more The ideal chain model assumes that polymer segments can overlap with each other as if the chain were a phantom chain. In reality, two segments cannot occupy the same space at the same time. This interaction between segments is called the See more The study of long chain polymers has been a source of problems within the realms of statistical mechanics since about the 1950s.
