Polymerization of Monomers with Multiple Double Bonds

Polymerizations of monomers with multiple double bonds yield products that vary according to the locations of these bonds with respect to each other. Monomers with conjugated double bonds, such as 1,3-butadiene and its derivatives, polymerize in two different ways. One way is through one of the double bonds only. Another way is through both double bonds simultaneously. Such 1,4 propagation is attributable to the effect of conjugation and hybridization of the C₂–C3 bond that involves sp2 hybrid orbitals [97]. All three modes of propagation are possible in one polymerization reaction so that the product can, in effect, be a copolymer. The 1,4, 1,2, and 3,4, placement in propagations can be illustration as follows:
