Abstract
Alpha-methyl-p-bromo-styrene prepared by the manipulative steps of brominating poly(.alpha.-methyl-styrene) and subsequently depolymerizing the brominated polymer. The alpha-methyl-p-bromo-styrene has particular utility as a co-monomer for preparing copolymers exhibiting a flame retardancy.
