A method of preparing MEP including the steps of: (a) adding N-methylpyrrolidine to an excess amount of ethyl bromide located in a reactor, wherein the N-methylpyrrolidine will react with the ethyl bromide forming MEP, wherein the reaction will have a reaction temperature that can varies over time; (b) stopping addition of N-methylpyrrolidine when the excess of ethyl bromide to the N-methylpyrrolidine falls within a range of 3:1 to 1.5:1; (c) adding water to the reactor creating a two phase system to develop which includes: (i) a top layer containing aqueous MEP and (ii) a bottom layer containing ethyl bromide; (d) separating the top layer from the bottom layer yielding a first aqueous solution of MEP and a second solution of ethyl bromide; and (e) removing N-methylpyrrolidine and ethyl bromide from the first aqueous solution of MEP.

This invention relates flame retardant compositions containing low molecular weight brominated anionic, chain transfer, vinyl aromatic polymers, hereinafter 'ACTVAP'. The compositions can accommodate high bromine content while still exhibiting a low thermally labile bromine content. The compositions have glass transition temperatures, T, that are predictive of acceptable melt flows and heat distortion temperatures (HDT) in HIPS and ABS based formulations substrates. The compositions, are suitable flame retardant candidates for use in thermoplastic formulations, e.g. polystyrene and ABS formulations.
