Reaction involving sites or groups on existing macromolecules or an interaction between existing macromolecules that results in the formation of a small region in a macromolecule from which at least four chains emanate.
Notes:
- The small region may be an atom, a group of atoms, or a number of branch points connected by bonds, groups of atoms, or @O04286@ chains.
- A reaction of a reactive chain end of a @L03554@ with an internal reactive site of another @L03554@ results in the formation of a branch point, but is not regarded as a crosslinking reaction.
