WebA linear polymer is obtained as the condensation product when both functional groups are difunctional. When one of the functional groups is tri- or tetra-functional, the polymer formed will be a cross-linked polymer … In chemistry, functionality is the presence of functional groups in a molecule. A monofunctional molecule possesses one functional group, a difunctional two, a trifunctional three, and so forth. In organic chemistry (and other fields of chemistry), a molecule's functionality has a decisive influence on its reactivity. In polymer chemistry, the functionality of a monomer refers to its number of polymerizable groups, …
