random-coil model
Quick Summary
The random-coil model is a structural model used to describe amorphous solids, particularly those composed of long-chain molecules known as polymers. These polymers form the basis of many common plastics. The model, first proposed by P.J. Flory, depicts the structure as a collection of intermeshed and entangled polymer chains. The configurations of these chains are statistically defined by a mathematical concept known as a three-dimensional random walk. This model is crucial for understanding the physical properties of polymeric materials. Polymerization itself involves monomers chemically combining to form these large polymer molecules, setting it apart from processes like crystallization.12
