Number of covalent bonds that a @[email protected] or monomeric unit in a macromolecule or @[email protected] can form with other reactants.
Notes:
- There are no monofunctional monomers.
- If \(f = 2\), a @[email protected] macromolecule or a @[email protected] can be formed.
- If \(f > 2\), a branch point can be formed leading to a branched macromolecule, a @[email protected] or a micronetwork.
- Ethene and ethylene glycol are examples of difunctional monomers, glycerol is an example of a trifunctional @[email protected], and divinylbenzene and pentaerythritol are examples of tetrafunctional monomers.
