A
macromolecule
or
oligomer molecule
capable of entering, through reactive groups, into further
polymerization
, thereby contributing more than one
monomeric unit
to at least one chain of the final macromolecule. A
pre-polymer
molecule capable of entering into further
polymerization
through reactive
end-groups
, often deliberately introduced, is known as a telechelic molecule.
