Toluene → alpha-Methylstyrene isopropenyltoluene

참여 물질

반응 단계

250 g α-methyl styrene (99.8% purity), 250 g isopropenyltoluene, and 500 g toluene were introduced into a three-mouthed flask, and mixed while boron trifluoride phenol complex was slowly added, and the material was then cooled under dry ice and acetone solvent and reacted for 3 hr at 20° C. Next, alkali was added to inactivate and remove the catalyst, and concentrated to remove the solvent and unreacted monomer, and α-methylstyrene-isopropenyltoluene copolymer was obtained as a residue. This polymer was designated Polymer B3, and its physical properties are listed in Table 2.
