description The invention relates to the field of modified diene-containing (co)polymers, in particular, to modified butadiene-styrene copolymers that can be used as flame retardants for polymer compositions based on expandable polystyrene. In particular, the invention relates to a modified diene-containing (co)polymer, a method for preparing thereof and the use of the same as a flame retardant for expandable polystyrene. The modified diene-containing (co)polymer according to the invention is characterized by a high heat resistance, in particular, a 5% weight loss temperature of at least 180° C., a molecular weight of at least 1500 g/mol, and a halogen content of at least 35 wt. % based on the total weight of the (co)polymer.
