Number of covalent bonds that a
monomer molecule or monomeric unit in a macromolecule or
oligomer molecule can form with other reactants.
Notes:
- There are no monofunctional monomers.
- If
,
a linear chain macromolecule or a macrocycle can be formed.
- If
,
a branch point can be formed leading to a branched macromolecule, a network or a micronetwork.
- Ethene and ethylene glycol are examples of difunctional monomers, glycerol
is an example of a trifunctional monomer, and divinylbenzene and pentaerythritol
are examples of tetrafunctional monomers.
