摘要

首次研究了偶氮(异丁腈)引发的2-(全氟己基)甲基丙烯酸乙酯(FHEMA)在市售链转移剂2-氰基-2-丙基二硫苯甲酸酯存在下，在三氟甲苯(TFT)或超临界二氧化碳(scCO2)中进行自由基聚合。发现在TFT或scCO2中，FHEMA聚合在均匀条件下进行，并通过加成-破碎机制进行可逆链转移。

Polymerization of 2-(Perfluorohexyl)ethyl Methacrylate in the Presence of 2-Cyano-2-propyl Dithiobenzoate in Supercritical CO2

The radical polymerization of 2-(perfluorohexyl)ethyl methacrylate (FHEMA) initiated by azobis(isobutyronitrile) in the presence of a commercially available chain transfer agent, 2-cyano-2-propyl dithiobenzoate, carried out in trifluorotoluene (TFT) or in supercritical carbon dioxide (scCO₂) was studied for the first time. The conditions were found under which the FHEMA polymerization in TFT or in scCO₂ proceeds under homogeneous conditions with reversible chain transfer via the addition–fragmentation mechanism.

期刊介绍： Doklady Chemistry is a journal that publishes new research in chemistry and chemical engineering of great significance. Initially the journal was a forum of the Russian Academy of Science and published only best contributions from Russia in the form of short articles. Now the journal welcomes submissions from any country in the English or Russian language. Every manuscript must be recommended by Russian or foreign members of the Russian Academy of Sciences.
