Coil-globule transition
In polymer physics, the coil–globule transition is the collapse of a macromolecule from an expanded coil state through an ideal coil state to a collapsed globule state, or vice-versa. The coil–globul...
Static light scattering
Static light scattering is a technique in physical chemistry that measures the intensity of the scattered light to obtain the average molecular weight Mw of a macromolecule like a polymer or a protein...
Zimm–Bragg model
In statistical mechanics, the Zimm–Bragg model is a helix-coil transition model that describes helix-coil transitions of macromolecules, usually polymer chains. Most models provide a reasonable approx...
Melt flow index
The melt flow index (MFI) is a measure of the ease of flow of the melt of a thermoplastic polymer. It is defined as the mass of polymer, in grams, flowing in ten minutes through a capillary of a speci...
Theta solvent
In a polymer solution, a theta solvent (or θ solvent) is a solvent in which polymer coils act like ideal chains, assuming exactly their random walk coil dimensions therefore in a good solvent the Mark...

Prince Earl Rouse, Jr. ( October 12, 1917 – August 10, 2003 ) was an American physical chemist.He obtained his PhD from the University of Illinois in 1941.Rouse is most famous for a 1953 publica...
Worm-like chain
The worm-like chain (WLC) model in polymer physics is used to describe the behavior of semi-flexible polymers; it is the continuous version of the Kratky-Porod model.
The WLC model envisions an is...
Gough–Joule effect
The Gough–Joule effect (a.k.a. Gow–Joule effect) is the tendency of elastomers to contract when heated if they are under tension. Elastomers that are not under tension do not see this effect. If an el...
Elastolefin
Elastolefin is a fibre composed of at least 95% (by weight) of macromolecules partially cross-linked, made of ethylene and at least one other olefin. When stretched to one and a half times its origina...
Polyurethane
Polyurethane (PUR and PU) is a polymer composed of a chain of organic units joined by carbamate (urethane) links. While most polyurethanes are thermosetting polymers that do not melt when heated, ther...
