ABSTRACT:
A controlled molecular weight polymer of styrene is provided having bromine substituted thereon. Control of molecular weight is achieved by the use of alpha-methyl styrene dimer as a chain transfer agent. The brominated polymer of styrene is useful as a flame retardant, particularly for polyamides giving improved properties including color retention after molding.
