LIVING CATIONIC POLYMERIZATION OF ISOBUTYL VINYL ETHER, .2. TELECHELICS BY CONTROLLED CHAIN TERMINATION AND THEIR APPLICATION TO THE SYNTHESIS OF BLOCKCOPOLYMERS

Living cationic polymerization of isobutul vinyl ether (IBVE), initiated by1-iodo-1-(2-methyl propyloxy)-ethane (1) and tetraalkylammonium perchlorate yields polymers of well defined molar masses and end groups. The controlled introduction of end groups was confirmed by a model reaction and was then applied to introduce and azo initiator function. The resulting polymeric initiator was used for the synthesis of a blockcopolymer. © 1990 Springer-Verlag.
