スチレンのテロメリ化反応

Abstract

The telomerization of styrene was carried out with various telogens, and under suitable conditions low-molecular weight telomers were formed. Among the several alkyl halides that were used as telogen of the free radical initiated resctions, especially such halides as iodoform, methylene iodide, and bromoform gave the telomers contained a few styrene units. Oligomers having some hydroxy gnoups were synthesized by the co-telomerization of styrene and β-hydroxyethyl-methacrylate in the isopropanol solution. The monomeric thlomer was obtained by the ionic telomerization of styrene and acetic acid systems. The effect of reaction time, kind and concentration of the catalyst, and ratio of reagents were investigated.
