Abstract
Scope and limitation of the vinyl ether polymerization initiated by NR (4)ClO(4)(KClO4;LiClO4)/CH3CHI-OR was discussed. Besides isobutyl viny l ether (IBVE), N-vinylcarbazole (NVC) and 2-chloroethyl vinyl ether ( CEVE) were initiated by NR(4)ClO(4)/CH3CHI-OR. These polymerizations e xhibited the characteristics of a living polymerization. However, in o rder to observe narrow molar mass distribution NVC was initiated with CH3CHI-OR, without salts. Block copolymers were synthesized by the met hod of sequential monomer addition (NVC, IBVE, CEVE). The PCEVE segmen t was modified by nucleophilic substitution, which allowed the synthes is of amphiphilic block copolymers.
