A
macromolecule comprising a
main chain with multiple trifunctional
branch points from each of which a linear
side-chain emanates.
Notes:
-
If the subchains between the branch points of the main chain and the terminal subchains
of the main chain are identical with respect to constitution and degree of polymerization,
and the side chains are identical with respect to constitution and degree of polymerization the macromolecule is termed a regular comb macromolecule.
-
If at least some of the branch points are of functionality greater than three, the
macromolecule may be termed a brush macromolecule.
