陽離子聚合反應為一種鏈增長聚合反應,反應中陽離子引發劑(cationic initiator)會將電荷轉移單體,使單體變得有反應性。而這個具反應性單體會與其他單體進行相似的反應,最後形成聚合物。.陽離子聚合反應中的這種單體,必須受具有提供電子取代基(electron-donating substituent)的烯烴(olefins)和雜環(heterocycles)限制。相似於陰離子聚合反應,陽離子聚合反應對反應中所使用的溶劑(solvent)非常敏感,特別是溶劑可形成游離離子(free ions)的能力,此能力決定了增長的陽離子鏈的反應性。陽離子聚合反應用於聚異丁烯(polyisobutylene)的產生(如:丁基橡膠用於輪胎的內胎)和聚N-乙烯基咔唑(N-vinylcarbazole,PVK) IUPAC definition離子聚合反應中的動力鏈攜帶者( kinetic-chain carriers)為陽離子。
