英文摘要	trans-1,4-selective coordination chain transfer polymerization of 1,3-butadiene was achieved by using a nd(oi-pr)(3)/mg(n-bu)(2) catalyst, affording polybutadienes having high trans-1,4 contents (ca. 96%), moderate molecular weight (m-n = 1.0-2.3 x 10(4)), and narrow polydispersity (m-w/m-n similar to 1.7). in the system, mg(n-bu)(2) acted as both a co-catalyst and a chain transfer agent, and the calculated transfer efficiencies of mg(n-bu)(2) were 27-34%. the produced living polybutadiene could further initiate the ring-opening polymerization of epsilon-cl/lactide to give tpb-b-pcl/pla copolymers in a controlled fashion. the crystalline amphiphilic copolymers (tpb-b-pcl/pla) were subsequently applied to investigate their self-assembly behavior by adding a selective solvent into a polymer/co-solvent solution. the polymer plates composed of a crystallized tpb core and pcl/pla brushes were obtained by the crystallization-driven self-assembly. moreover, the morphology of the polymers underwent change from nano-sized plates to micro-sized plates with increasing addition of the selective solvent.
