Small region in a macromolecule from which at least four chains emanate, and formed by reactions involving sites or groups on existing macromolecules or by interactions between existing macromolecules.

Note 1: The small region may be an atom, a group of atoms, or a number of branch points

connected by bonds, groups of atoms, or oligomeric chains.

Note 2: In the majority of cases, a crosslink is a covalent structure but the term is also used to describe sites of weaker chemical interactions, portions of crystallites, and even physical interactions and entanglements.
