报道了一种通用的、通用的合成策略，用于生产实际数量广泛的端苯基异、同远旋半晶聚乙烯和非晶无规半晶等规聚α-烯烃。苯基作为其他类远旋聚烯烃官能团的合成子，可以通过简单的高产聚合后反应“揭开”。聚烯烃-聚酯二嵌段共聚物和三嵌段共聚物的合成证明了这些材料作为聚烯烃基合成聚合物结构类别的构建模块的价值，这些共聚物在缩合相中采用微相分离的纳米结构中间相。
A general and versatile synthetic strategy for producing practical quantities of a wide range of phenyl-group-terminated hetero- and homotelechelic semicrystalline polyethenes and amorphous atactic and semicrystalline isotactic poly(α-olefins) is reported. The phenyl groups serve as synthons for functionalities of additional classes of telechelic polyolefins that can be “unmasked” through simple high yielding postpolymerization reactions. A demonstration of the value of these materials as building blocks for structural classes of polyolefin-based synthetic polymers was provided by syntheses of well-defined polyolefin-polyester di- and triblock copolymers that were shown to adopt microphase-segregated nanostructured mesophases in the condensed phase.
