Sustainable synthesis of fine chemicals and polymers using industrial chlorine chemistry

Autor: Yasuhiro Kohsaka, Daisuke Matsuura, Yoshikazu Kimura

Publikováno v: Communications Chemistry, Vol 7, Iss 1, Pp 1-10 (2024)

Abstract To achieve sustainable resource circulation, preparation of reactive species from stable compounds is unavoidable. Chlorine chemistry is an eco-friendly methodology to address this demand. Chlorine is industrially produced from sodium chlori

Vitrimer-like elastomers with rapid stress-relaxation by high-speed carboxy exchange through conjugate substitution reaction

Autor: Natsumi Nishiie, Ryo Kawatani, Sae Tezuka, Miu Mizuma, Mikihiro Hayashi, Yasuhiro Kohsaka

Publikováno v: Nature Communications, Vol 15, Iss 1, Pp 1-9 (2024)

Abstract We report vitrimer-like elastomers that exhibit significantly fast stress relaxation using carboxy exchange via the conjugate substitution reaction of α-(acyloxymethyl) acrylate skeletons. This network design is inspired by a small-molecule

Synthesis of Thermo-Responsive Polymer via Radical (Co)polymerization of N,N-Dimethyl-α-(hydroxymethyl)acrylamide with N,N-Diethylacrylamide

Autor: Yasuhiro Kohsaka, Yoshiaki Tanimoto

Publikováno v: Polymers, Vol 8, Iss 10, p 374 (2016)

α-Functionalized acrylamides have not been considered as an effective monomer design due to their poor polymerizability, although the analogues, α-functionalized acrylates, are attractive monomers of which polymers exhibit characteristic properties
