  • High density cationic polymer brushes from combined “click chemistry” and RAFT-mediated polymerization
    作者:Serkan Demirci、Tuncer Caykara

    formation of well‐defined polymer brushes, which subsequently resulted in the presence of free polymer chains in solution. The free polymer chains were isolated and used to estimate the molecular weights and polydispersity index of chains attached to the surface. In addition, by varying the polymerization time, we were able to obtain poly(VBTAC) brushes with grafting density up to 0.78 chains/nm2 with
    一种制备阳离子聚[[ ar[乙烯基苄基]三甲基氯化铵] [聚(VBTAC)]刷是通过“点击化学”和可逆加成-断裂链转移(RAFT)聚合技术结合使用的。最初,通过使用叠氮化物改性的硅片和炔基封端的4-氰基戊酸二硫代苯甲酸酯(CPAD)的点击反应,使用RAFT链转移剂对硅表面进行了改性。然后,通过RAFT介导的聚合,从固定在表面的CPAD上,在硅表面上制备了一系列具有不同分子量,厚度和接枝密度的聚(VBTAC)刷子。通过X射线光电子能谱,水接触角测量,掠角傅立叶变换红外光谱对CPAD在硅片上的固定和随后的聚合物形成进行了表征,原子力显微镜和椭偏分析。需要添加游离的CPAD才能形成定义明确的聚合物刷,随后导致溶液中存在游离的聚合物链。分离出游离的聚合物链,并用于估计附着在表面上的链的分子量和多分散指数。此外,通过改变聚合时间,我们可以获得接枝密度高达0.78链/ nm的聚(VBTAC)刷子2具有明显的针状结构均匀分布。©2012

    A well-defined block copolymer brush poly(glycidyl methacrylate)-graft-(poly(methyl methacrylate)-block- poly(oligo(ethylene glycol) methyl ether methacrylate)) (PGMA-g-(PMMA-b-POEGMA)) is synthesized via grafting from an approach based on a combination of click chemistry and reversible addition-fragmentation chain transfer (RAFT) polymerization.

    We report the synthesis of poly(2-ethyl-2-oxazoline)-based (PEtOx) nanoobjects by polymerization-induced self-assembly (PISA). First, well-defined PEtOx macromolecular chain transfer agents were synthesized by cationic ring-opening polymerization and click chemistry.

  • Efficient RAFT polymerization of N-(3-aminopropyl)methacrylamide hydrochloride using unprotected “clickable” chain transfer agents
    作者:Patrícia V. Mendonça、Arménio C. Serra、Anatoliy V. Popov、Tamaz Guliashvili、Jorge F.J. Coelho
    DOI:10.1016/j.reactfunctpolym.2014.04.001
    日期:2014.8
    The reversible addition fragmentation chain transfer (RAFT) of N-(3-aminopropyl)methacrylamide hydrochloride (APMA) using unprotected "clickable" chain transfer agents in water/dioxane mixtures is reported. The controlled character of the polymerization was confirmed by the linear increase of the polymer molecular weight with monomer conversion, the narrow molecular weight distribution (D < 1.1) and by chain extension experiments. The allcyne-terminated PAPMA was further functionalized by "click" chemistry with an azido-functionalized coumarin derivative. The method reported here will be useful for the preparation of novel PAPMA based materials for biomedical applications using a strategy that does not require challenging protection/deprotection steps.
