Acetylene dangling bonds

In summary, the addition of H2O, N2, CO, or various combinations of these unusual comonomers to a plasma polymerization of acetylene produces chemically distinct polymers. The copolymerization of H2O reduces the quantity of dangling bond in a remarkable manner, as shown in Figure 7.14, and enhances the stability of the polymers.
