METHOD FOR PURIFYING α-METHYLSTYRENE AND HEAT-RESISTANT STYRENE-BASED COPOLYMER USING THE α-METHYLSTYRENE

摘要

An object of the present invention is to provide highly pure a-methylstyrene by efficiently removing polar substances present in the a-methylstyrene. The present invention discloses a method for purifying a-methylstyrene by reacting polar substances contained in the a-methylstyrene in the presence of a basic substance, and separating a reaction product of the polar substance and the α-methylstyrene.
