Copolymerization with monomers and their complexes

When donor—acceptor complexes are formed from the monomers, they can take part in copolymerization. When the equilibrium constants of complex formation are not extremely high, both complexes and monomers coexist and compete with active centres in the reaction. In addition, the reverse case may occur when one part of the active centres forms complexes with some component of the medium, the reactivity of the complexed centers is, of course, different from that of the free centres. The situation is formally similar to that of the preceding paragraph. 

Let us present an illustrative example. Shaikhutdinov et al. observed that small amounts of naphthalene, anthracene or chrysene in a mixture of butyl vinyl ether and methyl methacrylate significantly increase the contents of the
