The synthesis of stereoregular telechelic polypropylene (PP) and their use to access triblock amphiphilic copolymers with the PP block located in the center is described. The strategy consists of selectively copolymerizing propylene and a di‐functional co‐monomer (1,3‐diisopropenylbenzene) to yield a α,ω‐substituted polypropylene. Initiation of the copolymerization favors insertion of DIB over propylene; propagation steps favor insertion of propylene. Termination via a chain‐transfer reaction yields the terminal unsaturation of the polymer. The telechelic polypropylene is then converted into α,ω‐hydroxyl‐terminated polypropylene and used as a macroinitiator for the synthesis of triblock copolymers. Water‐soluble amphiphilic triblock polymers are also synthesized. The use of catalytic reactions simultaneously provides the stereocontrol of the polypropylene and high productivity (multiple chains of block copolymer per metal center).
