WebJul 15, 2024 · Linear chain polymers are repeating structures with the chemical formula \((A)\ns_x\), where \(A\) is the formula unit and \(x\) is the degree of polymerization. In many cases (polystyrene), \(x\gtwid 10^5\) is not uncommon. For a very readable introduction to the subject, see P. G. de Gennes, Scaling Concepts in Polymer Physics. WebThis handbook is a valuable resource in the design and operation of many polymer processes, such as polymerization, devolatilization, drying, extrusion, and heat exchange. …
WebPolymer thermodynamics are described by the Gibbs free energy which consists of two main contributions: one entropic part (combinatorial mixing of the monomers) and an enthalpic part (interactions between monomers). The Flory-Huggins equation for polymer blends gives a simple expression for the
