Steric gearing

網頁Ionic polymerizations are chain-growth reactions and can be anionic or cationic. • Free radical polymerizations have “free” growing chains that can lead to more defects (branches, head-to-head repeat units, variation in molecular weight) • Coordination, anionic and cationic methods keep the active end of the growing chain held in a specific position.
