2012年3月29日 · A series of 2,2′-bipyridines with 4,4′-substituents (R-bpy) were investigated for atom transfer radical polymerization (ATRP) of methyl acrylate (MA) and methyl methacrylate (MMA).

2013年8月30日 · The bulk ATRP of styrene can be well controlled by optimizing the polymerization conditions such as temperature, initiators, catalysts, and ligands. Using 1-PEBr as the initiator, CuBr as the catalyst, and PMDETA as the ligand, the bulk ATRP of styrene can be satisfactorily achieved at 90°C.

ABSTRACT: The synthesis of well-defined polystyrene by atom transfer radical polymerization (ATRP) is reported. The effects of temperature, initiators, catalysts, and ligands on styrene bulk ATRP were investigated in detail. Results indicated that the initiator

2021年11月9日 · The novel approach for conducting ARGET ATRP based on simultaneous use of two copper complexes based on tris[2-(dimethylamino)ethyl]amine (Me 6 TREN), 2,2’-bipyridine (bipy) and tris(2-pyridylmethyl)amine (TPMA) in one pot is proposed. This approach allows to increase the rate of polymerization of acrylonitrile and to achieve polymers with ...

We demonstrate that the successful ATRP of MAIPGal can be achieved for 2-EBiB/CuBr/bipy and 2-MBP/CuCl/bipy at 60 °C and for 2-EBiB/CuBr/PMDETA at room temperature. The initiation by 2-EBiB at room temperature with PMDETA as the ligand should be the most optimum operation for its moderate condition and suppression of many side reactions.

原子转移自由基聚合( ATRP，Atomic transfer radical polymerization ) 是可逆失活自由基聚合的一个例子。 与其对应物ATRA或原子转移自由基加成一样，ATRP 是一种利用过渡金属催化剂形成碳碳键的方法。

2023年8月30日 · 原子转移自由基聚合 (ATRP)是一种重要的“活性”/可控自由基聚合方法，它通过对聚合体系中大量的高反应活性的自由基可逆去活性化，避免了聚合反应中不可逆的链转移、链终止等反应，实现了对聚合过程的控制，由此获得具有精确可控分子量及窄分子量分布的聚合物 …

采用CuBr/bpy(PMDETA)催化剂和1-苯基溴乙烷通过原子转移自由基聚合(ATRP)成功合成了功能明确的聚(对苯基苯乙烯磺酸盐)和聚(对苯基苯乙烯磺酸盐-共聚苯乙烯) (1-PEBr) 在二苯醚 (DPE) 或二甲基甲酰胺 (DMF) 中作为 ATRP 引发剂。在均聚物和共聚物中，DPE 或 DME 中的 CuBr ...

2017年3月28日 · Electrochemically mediated atom transfer radical polymerization (eATRP) initiates/controls the controlled/living ATRP chain propagation process by electrochemically generating (regenerating) the activator (lower-oxidation-state metal complex) from deactivator (higher-oxidation-state metal complex).

2016年6月1日 · We herein report the ATRP of isoprene and the block copolymerization of isoprene with styrene for the synthesis of polyisoprene-b-polystyrene block copolymer (PS-b-PIP) using CuBr/2,2′-bipyridine (CuBr/Bpy) as a catalyst and methyl 2 …
