Abstract
This paper reports the synthesis and characterization of azo functiona l poly(isobutyl vinyl ether) oligomers and block copolymers containing poly(isobutyl vinyl ether) and oligoesterdiol segments. Isobutyl viny l ether was polymerized using a trifluoromethanesulfonic acid/tetrahyd rothiophene initiating system in dichloromethane at -30 degrees C, and quantitatively terminated with labile azo compounds to give poly(isob utyl vinyl ether) with well-defined molecular weight and end-groups. A lso, diblock copolymers with poly(isobutyl vinyl ether) and oligoester diol segments were synthesized by termination of living, cationically polymerized isobutyl vinyl ether with oligoesterdiol.
