Abstract

Synthesis of thermoresponsive block and graft copolymers via the combination of living cationic polymerization and RAFT polymerization using a vinyl ether-type RAFT agent

Polymer Synthesis with More Than One Form of Living Polymerization Method

“…Sugihara and co‐workers described the synthesis of block copolymers using a combination of living cationic polymerization and RAFT polymerization employing benzyl 2‐(vinyloxy)ethyl carbonotrithioate (BVCT), a vinyl ether‐type RAFT agent . This process takes advantage of the BVCT‐trifluoracetic acid adduct (BVCT‐TFA) to initiate the cationic polymerization of vinyl ether of the RAFT agent to give the macro‐chain transfer agent (CTA) which in turn allows the RAFT polymerization to proceed.…”

Synthesis of PMMA-b-PEG-b- PMMA by controlled Polymerization Using Macro-RAFT Agents

“…Because of this reason, intensive studies have been carried out in recent years by means of polymerization methods which have well defined, and some narrow molecular weight and allow the desired functional groups have been added to the structure because of controlled polymerization of polymers. (Hemp, Smith et al, 2014, Ma'Radzi, Sugihara et al, 2014, Li, Ding et al, 2017.…”

(Hemp, Smith et al, 2014, Ma'Radzi, Sugihara et al, 2014, Li, Ding et al, 2017. Independed radical polymerization; is a polymerization carried out on easy experimental conditions, in which most of the vinyl monomers can be polymerized with the most industrial applications (Yan, Lin et al, 2017, Liu andHobbs 2018).…”

“…Among the controlled / living radical polymerization techniques discovered in the last twenty years, nitroxide-mediated polymerization ATRP (Neugebauer 2015, Chmielarz 2016, Liu and Hobbs 2018, nitroxidemediated polymerization, NMP (Nicolas, Guillaneuf et al, 2013, Kermagoret and Gigmes 2016, Ballard, Aguirre et al, 2017and reversible addition-removal chain transfer (RAFT) (West, Barner-Kowollik et al, 2010, Yeole and Hundiwale 2011, Ma'Radzi, Sugihara et al, 2014, Sütekin and Güven 2018polymerization techniques have been used extensively in molecular architecture design. Sensitive polymer very welldefined displaying Molecular weight distributions, high end group suitability and various complex architectures are unique for the synthesis of materials.…”
