difunctional comonomer
Clearly the principle requirement for a substance to be capable of forming a structural unit of a polymer chain is that it must be difunctional.
By definition an exclusively difunctional monomer can only give rise to a linear polymer.
Such a process is particularly useful in the production of difunctional monomers and intermediates in the synthesis of adipic acid.
