The synthesis of a linear polyisobutylene is achieved for the first time by free radical polymerization. reaction was performed in environmentally friendly conditions, i.e., an aqueous medium using cyclodextrin solubilizer, around room temperature. This mild and straightforward polymerization resulted predominantly polymer with low dispersity. Isobutylene also copolymerized acrylamide via this ...

Electron spin resonance studies of the in vivo response to fungicides (chloranil and thiram) by Aspergillus niger of different ages are described. The spores possessed a natural free radical signal which grew rapidly upon application of chloranil. Thiram, on the other hand, produced weak changes in the free radical region but easily detectable changes at lower fields, indicating involvement of ...

A new general reaction for the preparation of isomerically pure hydroxyalkylated C(60) monoadducts, via the free radical photochemical addition of alcohols to [60]fullerene, is described.

multiwalled carbon nanotubes (mwcnts) have been functionalized with -so3h groups using new three steps chemical routes. firstly, oh groups have been attached to cnt surfaces through a radical reaction. the second step involves converting the hydroxyl groups into the oxide one and last step included the attachment of –so3h groups on the mwcnts surfaces in the presence of 1-butyl-3-methyl imidazo...
