Macromonomer molecule: A macromolecule that has one end-group which
enables it to act as a monomer molecule, contributing only a single monomeric unit
to a chain of the final macromolecule.
A macromonomer is a macromolecule with one end-group that enables it to act as a monomer. Macromonomers will contribute a single monomeric unit to a chain of the completed macromolecule.
