Allgemeine Beschreibung

Radikalstarter

Anwendung

  • Polymer Chemistry: Analysis of polymer synthesis using AIBN under various conditions, with emphasis on thermal initiation properties (Suriyanarayanan & Nicholls, 2019).
  • Influence of cyclodextrin on the UCST-and LCST-behavior of poly (2-methacrylamido-caprolactam)-co-(N, N-dimethylacrylamide): Explores the role of AIBN in copolymerization processes influencing polymer properties relevant to material science applications (Burkhart & Ritter, 2014).
  • Preparation and characterization of polyaniline microcapsule loaded with 2, 2′‐azobis (2‐methylpropionitrile) initiator and its controlled release: Demonstrates innovative applications of AIBN in microencapsulation techniques, targeting enhanced performance in adhesive industries (Zhang et al., 2022).

In the presence of a catalytic amount of radical initiator AIBN, primary amines are oxidatively coupled to imines and tertiary amines are cyanated to α-aminonitriles. These "metal-free" aerobic oxidative coupling reactions may find applications in a wide range of "green"

Quercetin, the most abundant flavonoid in dietary fruits and vegetables, acts as antioxidant or prooxidant depending on the environmental conditions. The antioxidant behavior is believed to involve initial oxidative steps with subsequent changes in the flavonoid skeleton, which ultimately alters

We have developed new urethane acrylate-based root canal sealers using polycarbonate (PC) as polyol and 2,2-azobis(2-methyl)butyronitrile (AMBN) as a thermal initiator. The purpose of this study was to compare the properties among a group of seven sealers: (1) polybutyleneadipate (PBA)

A novel class of nonionic amphipols (NAPols) designed to handle membrane proteins in aqueous solutions has been synthesized, and its solution properties have been examined. These were synthesized through free radical cotelomerization of glucose-based hydrophilic and amphiphilic monomers derived from
