Abstract: An aminoalkoxystyrene represented by the formula (1) wherein R 1 and R 2 are C 1-4 alkyl 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.

Abstract: PROBLEM TO BE SOLVED: To provide an economically advantageous distillation method capable of preparing a high quality oxystyrene derivative such as PTBS (p-tert-butoxystyrene), PACS (p-acetoxystyrene) or MTBS (m-tert-butoxystyrene) at a high recovery rate, which derivative is inhibited in discoloration and thus has dissolved conventional problems in the prior art, by inhibiting the decomposition and discoloration of the oxystyrene derivative and a polymerization inhibitor, without impairing a polymerization inhibiting effect of a nitroso compound or a nitro compound which is a polymerization inhibitor.
SOLUTION: In a method comprising distilling an oxystyrene derivative in the presence of a nitroso compound and/or a nitro compound, the distillation is carried out in the coexistence of an epoxy compound.

Abstract: PURPOSE:To enable effective decoloration of a colored nucleus-brominated styrene on an industrial scale at a low cost by dissolving the crude brominated styrene in an aliphatic hydrocarbon and contacting with a specific adsorbent such as oxides composed mainly of silica or alumina. CONSTITUTION:A colored nucleus-brominated styrene (BS) is dissolved in a cyclic or chain saturated aliphatic hydrocarbon having a carbon number of about 5-8 (especially hexane, heptane or octane) and made to contact with one or more kinds of adsorbents selected from (a) oxide composed mainly of silica or alumina, (b) carbonate, phosphate or silicate of calcium or magnesium and (c) amorphous carbon. The BS can effectively be decolored by this process. A BS which does not cause discoloration of a resin molded article after polymerization, especially mono-to tribromostyrene useful as a reactive flame-retardant or monomer for a polymeric material can be produced with a simple procedure by a process having high industrial utilization value and practicability at a low cost.
