“…The ring-opening polymerization (ROP) technique was firstly carried out by Carothers et al for lactones, cyclic anhydrides and carbonates (Hizal, et al, 2005;Coulembier, et al, 2006;Çatıker, et al, 2020;). ROP technique was widely used in the syntheses of new types of copolymers (Coulembier, et al, 2006;Göktaş et al, 2014;Öztürk, Yavuz, et al, 2016;. The applications in "click" chemistry have been examined (Moses and Moorhouse, 2007;Xu et al, 2007;Altıntas and Tunca, 2011;Tunca, 2013;Xi et al, 2014;Zhu et al, 2015;Öztürk and Meyvacı 2017; since "click" chemistry was presented by Sharpless et al (Kolb et al, 2001) in 2001.…”

“…To overcome these disadvantages, simpler and easier techniques have been used recently for block copolymer synthesis [8,9]. It has been possible to be successful in block copolymer synthesis in recent years with RAFT-ROP [10], ATRP-ROP [11], and redox polymerization-ATRP methods which have many advantages compared to other popular methods and have been implemented by using different techniques together [12]. Due to the practicability of two transformations at the same time or through separate steps, it minimizes homopolymerization which causes side reactions.…”

In this study, block copolymer synthesis was evaluated by combining the redox polymerization technique and different polymerization techniques. By combining such different polymerization techniques, block copolymer synthesis has recently become an important part of polymer synthesis and polymer technology. The block/ graft copolymers synthesized by combining such different techniques contribute greatly to macromolecular engineering. In today's polymer synthesis, copolymer synthesis is of great interest in polymer technologies especially by using controlled radical polymerization and different polymerization techniques together. The success achieved in copolymer synthesis by using different polymerization techniques such as ATRP-ROP, RAFT-ROP, and ATRP-RAFT on the same step or different steps was achieved by combining redox polymerization with moderate polymerization conditions and controlled radical polymerization techniques as well.

“…"Click" chemistry applications have been available until now [2][3][4][5][6][7][8][9][10][11][12][13][14][15]. Macromolecules are used in technological applications and theoretical studies [16][17][18][19][20][21]. Polymers based on polyethylene glycol (PEG) are attractive materials for biomedical, industrial, and chemicals applications, as PEG has unparalleled characters such as superior ion absorbability, flexibility, hydrophilicity, and biocompatibility [22][23][24][25][26][27][28][29][30][31].…”

Synthesis of ring-type (or branched) polymers including polyethylene glycols was archived via "click" chemistry of 5,6-diazido-2-benzyl-1H-benzimidazole (Di-N 3) [or triazidoacetohydrazide derivative (Tri-N 3)] and terminally dipropargyl polyethylene glycols (PEG-dipropargyl) with different molecular weights. DiN 3 was obtained by reaction of 5,6-dichloro-2-benzyl-1H-benzimidazole (Di-Cl) and sodium azide. 2-(2-benzyl-5,6-dichloro-1H-benzimidazol-1-yl)-N′-(4-chlorobenzylidene)acetohydrazide (Tri-Cl) was synthesized by using Di-Cl. Synthesis of Tri-N 3 was archived by means of reaction of Tri-Cl and sodium azide. PEG-dipropargyl was synthesized by using reaction of PEGs with different molecular weights and propargyl chloride. By using DiN 3 (or Tri-N 3) and PEG-dipropargyl, ring-type (or branched) polymers including polyethylene glycols were synthesized. The polymers were relatively acquired in high yields and low dispersities. The primary parameters for example concentration and time were assessed. The characterization of products was accomplished by using multi instruments such as 1 H-NMR, FT-IR, GPC, TGA, DSC, and elemental analysis techniques. The multi instruments studies of the obtained polymers show that the ring-type and branched polymers easily formed as a result of "click" chemistry.
