Direct incorporation of gaseous carbon dioxide into solid‐state copolymer containing oxirane and quaternary ammonium halide structure as self‐catalytic function

Abstract

We established a self‐catalyst system for solid phase incorporation of gaseous carbon dioxide into terpolymers prepared by polymerization of glycidyl methacrylate, N‐benzyl‐N‐[2‐(methacryrolroxy)ethyl]‐N,N‐dimethylammonium bromide, and methyl methacrylate. Terpolymer composition affected the incorporation behavior where the terpolymer with higher oxirane content exhibited higher efficiency of carbon dioxide incorporation. © 2004 Wiley Periodicals, Inc.

Facile synthesis of polymers bearing cyclic carbonate structure through radical solution and precipitation polymerizations accompanied by concurrent carbon dioxide fixation

“…The reaction of carbon dioxide and epoxides affording five‐membered cyclic carbonates is a good candidate owing to its relatively mild conditions 7–14. This reaction has been employed for synthesis of various polymers, but multiple steps were required 15–34. In this point of view, we recently reported a combined system comprising carbon dioxide fixation and radical polymerization through radical polymerization of glycidyl methacrylate (GMA) under a carbon dioxide atmosphere (1 atm) 35.…”

Consensus equals mediocrity. There, I said it!

“…The reaction of CO 2 and epoxides giving five‐membered cyclic carbonates is a good candidate owing to its relatively mild conditions 1–8. This reaction has been used for syntheses of various polymers, but multiple steps were required 9–30. In this point of view, we recently reported a combined system comprising carbon dioxide fixation and radical polymerization through radical polymerization of glycidyl methacrylate (GMA) under a carbon dioxide atmosphere at 1 atm 31, 32.…”

“…The resulting polymers are homopolymers or copolymers of GMA and 1,3‐dioxolan‐2‐one‐4‐ylmethyl methacrylate (DOMA), whose ratios can be controlled by the reaction conditions. The obtained polymers are potentially applicable to paints, adhesives, optical materials, and polymeric supports for lithium ion batteries 9–23. The advantages of this combined reaction are the facileness, the shorter time for the reaction itself, and the controllable unit ratios of the carbonate and oxirane moieties (carbonate content = 18–100%).…”

Aortic valve in valve insertion: A note of caution and a case for possible optimism

“…Recently, various types of ionic liquids1, 2 have been investigated as novel nonvolatile and nonflammable functional materials, such as ionic conductive materials and environmentally benign solvents (a reaction medium), playing an important role in the field of environmental chemistry. These characteristics have also prompted much research on the synthesis and properties of polymers with ionic liquid moieties or similar structures 3–19. With regard to stimuli‐responsive behavior, an upper critical solution temperature (UCST)‐type phase separation of sulfobetaine polymers in water was reported 20.…”
