| titleOfInvention |
Novel 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: n n n comprising: n (a) contacting a cycloalkene with a chain transfer agent of the formula: n Z—Y═Y—Z n in the presence of a metal carbene metathesis catalyst to form a telechelic polymer; and n (d) contacting the telechelic polymer with an alkene of the formula n n n in the presence of an ATRP organometallic catalyst n wherein 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 C 1 -C 20 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. |
