The area is of particular importance in the making of composites, coatings, and adhesives by thermosetting cure reactions in which multifunctional molecules of low molecular weight are converted into network macromolecules. An attempt has been made to produce a generalized model for the formation and properties of thermosetting systems which also incorporates linear systems: an example of the former is the cure of a neat epoxy resin; an example of the latter is the polymerization of neat styrene monomer below the glass transition of polystyrene. This article will therefore emphasize thermosetting systems with some reference to linear systems. The simplest model for chemical setting assumes a single reaction mechanism and no phase separation. 收起
