"Co-polymers" consist of two different monomers ("a" and "b") joined in an alternating fashion (ababab...). Block co-polymers also consist of two different monomers, but in this case blocks of polymer containing only a units are joined to blocks of polymer containing only b units (aaaaabbbbb...). How might block co-polymers be synthesized? : Polymer Chemistry
