Resumen:

In this chapter, the authors define several terms related to polymer network formation; they also examine general aspects of some of the existing gelation theories and describe some aspects related to polymer network formation by copolymerization with crosslinking of vinyl/divinyl monomers. A polymer network can be envisioned as a polymer molecule with an infinite molecular weight. Crosslinking is a physical or chemical route by which polymers with branched or crosslinked structures are produced. The chemical route may imply a polymerization or postpolymerization stage. From a general point of view, chemical crosslinking processes can be classified into four major types of reactions: step-growth polymerization, free radical polymerization, vulcanization, and end-linking of prepolymers. A few aspects of polymer network characterization are summarized in the chapter. Finally, the chapter discusses the theories and mathematical models of crosslinking. © 2013 John Wiley & Sons, Inc.
