An aminoalkoxystyrene represented by the formula (1) wherein Rand Rare Calkyl and n is 3-6. The aminoalkoxystyrene is prepared by reacting an aminoalkoxyphenylmagnesium halide with vinyl halide in the presence of a catalyst. A quaternized amino group-containing polymer made by quaternizing the amino groups of a polymer prepared from the aminoalkoxystyrene is useful as an anion exchanger.

Aminoalkoxystyrene, process for preparation thereof, polymer thereof, process for producing the polymer and use thereof

A process for the production of a styrene derivative is provided. The process comprises reacting a Grignard reagent prepared from an aromatic halogen compound with a vinyl halide in the presence of a catalyst, wherein the catalyst is at least one member selected from the group consisting of manganese catlyst, iron catalyst, cobalt catalyst and rhodium catalyst.

Process for the production of styrene derivative

A process for the production of a styrene compound is provided. The process comprises reacting a Grignard reagent prepared from a tertiary butoxyphenyl halide with a vinyl halide in the presence of a catalyst, wherein the catalyst is at least one member selected from the group consisting of manganese catalyst, iron catalyst, cobalt catalyst and rhodium catalyst. The process overcomes the problems involved in the prior art, and is economical and safe. The styrene compound by the process is free from biphenyl.
