摘要: “Perfect comb” graft copolymers are synthesized via acyclic diene metathesis (ADMET) polymerization using well-defined ruthenium catalyst systems to yield precisely spaced polyethers along an unsaturated polyolefin backbone. The is placed in a symmetrical α,ω-diene prior ADMET ensure exact placement at each functional site the polymer backboneno mistakes made. polyether grafts essentially monodisperse as shown by MALDI analysis, while backbone exhibits dispersity of 2.0. Such poly(ethylene-graft-ethylene oxide) will be interesting several applications.
