Chapter 26.2C, Problem 26.9P
Chain branching is not as common with anionic
- a. Propose a mechanism for chain branching in the polymerization of acrylonitrile.
- b. Compare the relative stabilities of the intermediates in this mechanism with those you drew for chain branching in the cationic polymerization of styrene (Problem26-6). Explain why chain branching is less common in this anionic polymerization.
