Recent Advances In Cationic Polymerization

Fast living cationic polymerization of vinyl ethers with iron(III) chloride in the presence of a cyclic ether: Most active and environmentally benign catalyst for the living cationic polymerization of vinyl ethers

“…Although there are several examples of cati-onic polymerization of vinyl ethers, 15 styrenes, 16 and dienes 17 with FeCl 3 , living cationic polymerization has not been reported. 18 Here we report the living cationic polymerization of an alkyl vinyl ether with an FeCl 3 /cyclic ether initiating system. Previous studies have shown that a weaker base induces faster living polymerization.…”
