also contains definitions of: n-star macromolecule, regular star macromolecule, variegated star macromolecule
https://doi.org/10.1351/goldbook.S05935
A macromolecule containing a single branch point from which linear chains (arms) emanate.
Notes:
  1. A star macromolecule with n linear chains (arms) attached to the branch point is termed an n-star macromolecule, e.g. five-star macromolecule.
  2. If the arms of a star macromolecule are identical with respect to constitution and degree of polymerization, the macromolecule is termed a regular star macromolecule.
  3. If different arms of a star macromolecule are composed of different monomeric units, the macromolecule is termed a variegated star macromolecule.
