ABA triblock and diblock copolymers and methods of preparing the same |
| abstract |
The invention discloses a method for preparing a triblock copolymer of the formula:comprising:(a) contacting a cycloalkene with a chain transfer agent of the formula:in the presence of a metal carbene metathesis catalyst to form a telechelic polymer; and(d) contacting the telechelic polymer with an alkene of the formulain the presence of an ATRP organometallic catalystwherein n and m are integers; Z is an ATRP initiator and -Y=Y- is an alkenyl group; and, R' is selected from the group consisting of aryl, nitrile and C1-C20 carboxylate, wherein R' is substituted or unsubstituted. The invention also discloses a method for preparing a diblock copolymer. In addition, the invention encompasses a triblock copolymer having no 1,2-PBD structure in the PBD portion of the copolymer. |
