通过6-甲基-1，2-庚二烯-4-醇的活性配位聚合和甲基丙烯酸甲酯的原子转移自由基聚合相结合，合成了一系列具有聚丙二烯主链和聚甲基丙烯酸甲酯侧链的接枝共聚物。我们首先以[（η3-allyl）NiOCOCF 3]2为引发剂，通过活性配位聚合反应，以6-甲基-1，2-庚二烯-4-醇为原料合成了含聚联烯重复单元的聚醇，然后将侧链羟基转化为含卤素的ATRP引发基团。然后，采用自接枝法合成了具有良好溶解性的接枝共聚物：通过甲基丙烯酸甲酯的ATRP将聚甲基丙烯酸甲酯接枝到主链上。这类接枝共聚物是通过丙二烯衍生物和甲基丙烯酸类单体接枝共聚物的第一个例子。
A series of well-defined graft copolymers with a polyallene-based backbone and poly(methyl methacrylate) side chains were synthesized by the combination of living coordination polymerization of 6-methyl-1,2-heptadien-4-ol and atom transfer radical polymerization of methyl methacrylate. We first prepared poly(alcohol) with polyallene repeating units via 6-methyl-1,2-heptadien-4-ol by living coordination polymerization initiated by [(η3-allyl)NiOCOCF3]2, followed by transforming the pendant hydroxyl groups into halogen-containing ATRP initiation groups. Next, grafting-from route was used for the synthesis of the well-defined graft copolymer with excellent solubility: poly(methyl methacrylate) was grafted to the backbone via ATRP of methyl methacrylate. This kind of graft copolymer is the first example of graft copolymer via allene derivative and methacrylic monomer.
