A cross-link suggests a branch point from which four or more distinct chains emanate. A polymer molecule with a high degree of cross-linking is referred to as a polymer network. Sufficiently high cross-link concentrations may lead to the formation of an infinite network, also known as a gel, in which networks of chains are of unlimited extent—essentially all chains have linked into one molecule.
