A macromolecule containing a single branch point from which linear chains (arms) emanate.
- A star macromolecule with \(n\) linear chains (arms) attached to the branch point is termed an \(n\)-star macromolecule, e.g. five-star macromolecule.
- If the arms of a star macromolecule are identical with respect to @C01282@ and @D01569@, the macromolecule is termed a regular star macromolecule.
- If different arms of a star macromolecule are composed of different monomeric units, the macromolecule is termed a variegated star macromolecule.
