    • There is provided a novel hyperbranched polymer in which the refractive index is precisely controlled while retaining its hyperbranched structure, and a method for producing the hyperbranched polymer. Further, there is also provided an optically and thermally stable novel hyperbranched polymer in which the desired refractive index is precisely controlled, and a method for producing the hyperbranched polymer. The hyperbranched polymer has, as a branched structure, a repeating unit structure produced from two dithiocarbamate compounds each having a vinyl structure, at the polymerization initiation site having a vinyl structure. A specific example of the hyperbranched polymer can be produced by subjecting to a living radical polymerization N,N-diethyldithiocarbamylmethylstyrene in the presence of N,N-diethyldithiocarbamylethyl methacrylate.
    • 提供了一种新颖的超支化聚合物,其中折射率被精确地控制,同时保持其超支化结构,以及制备超支化聚合物的方法。 此外,还提供了光学和热稳定的新型超支化聚合物,其中精确控制所需的折射率,以及制备超支化聚合物的方法。 超支化聚合物作为支链结构具有由具有乙烯基结构的两个二硫代氨基甲酸酯化合物产生的重复单元结构,在聚合引发部位具有乙烯基结构。 超支化聚合物的具体实例可以通过在N,N-二乙基二硫代氨基甲酰基乙基甲基丙烯酸酯的存在下进行活性自由基聚合N,N-二乙基二硫代氨基甲酰基苯乙烯来制备。

    • A one-pot polymerization process of preparing long chain branching polymers is provided. Also described is a “T” reagent that serves as a link between main and side chains of an inventive long chain branching polymer. A “T” reagent has at least two functionalities, serving as both co-monomer and chain transfer reaction agent. Optionally, a copolymerization reaction between an alpha-olefin and “T” reagent takes place initially to incorporate some “T” molecules in the polyolefin main chain, and the incorporated “T” units then behave as chain transfer agents for reacting with the propagating polyolefin chains to form side chains. In a particular embodiment, a polymerization process for preparing long chain branching polyethylene (LCBPE) and long chain branching polypropylene (LCBPP) is detailed.
    • 提供了制备长链支化聚合物的一锅聚合方法。 还描述了作为本发明的长链支化聚合物的主链和侧链之间的连接的“T”试剂。 “T”试剂具有至少两种用作共聚单体和链转移反应剂的功能。 可选地,首先在α-烯烃和“T”试剂之间进行共聚反应,以在聚烯烃主链中加入一些“T”分子,然后加入的“T”单元表现为用于与传播聚烯烃反应的链转移剂 链形成侧链。 在具体实施方案中,详细描述了制备长支链聚乙烯(LCBPE)和长链支化聚丙烯(LCBPP)的聚合方法。
