MODIFIED (CO)POLYMER, METHOD FOR PREPARING THEREOF AND USE OF THE SAME

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 DEG 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. 本发明涉及改性的含二烯的(共聚)聚合物的领域，特别地，涉及可以用作基于可发泡聚苯乙烯的聚合物组合物用阻燃剂的改性丁二烯-苯乙烯共聚物。特别地，本发明涉及改性的含二烯的(共聚)聚合物、用于制备其的方法和其作为可发泡聚苯乙烯用阻燃剂的用途。根据本发明的改性的含二烯的(共聚)聚合物的特征在于高耐热性，特别地，至少180℃的5％重量损失温度，至少1500g/mol的分子量，以及基于(共聚)聚合物的总重量至少35重量％的卤素含量。
