Synthesis of manganese ferrite nanoparticles in macroporous styrene-divinylbenzene copolymer

Journal of Magnetism and Magnetic Materials, 2004
Abstract Preparation of manganese ferrite (MnFe 2 O 4 ) in a polymer template is described in this work. The ferrite-based samples were prepared in situ by two routes: (I) alkaline oxidation of Fe 3+ and Mn 2+ ions and (II) alkaline oxidation of Fe 2+ and Mn 2+ ions. The nanocomposites were characterized using chemical analysis, X-ray diffraction,

Catalytic properties of cobalt(II) porphyrins supported on styrene-divinylbenzene copolymer

Journal of Applied Polymer Science, 1996
Polymeric pyridinium chloride was synthesized by treating pyridine with 2% divinylbenzene (DVB)-crosslinked chloromethyl polystyrene. Sodium 5,10,15,20-tetrakis(4-sulfophenyl)porphyrin was synthesized and appended on the above polymer through an ionic linkage.

Styrene‐divinylbenzene copolymers for high‐performance proppant applications

Polymer Engineering & Science
AbstractThis study focuses on developing and characterizing polymer‐based materials for high‐performance applications as proppants in oil and gas wells. We use styrene‐divinylbenzene (Sty‐DVB) copolymers as the base, incorporating additives such as polybutadiene (PB) and polyphenylene oxide (PPO).

Temperature effect on tension formation in styrene–divinylbenzene copolymers

Polymer International
AbstractCrosslinked polymers are considered to be promising materials for supporting catalysts that are effectively applied in different reactions. However, the application of polymer‐supported catalysts in high‐temperature processes is limited by their temperature stability.
