The present invention relates to a polymer composition comprising: a silane functionalized polyolefin; a brominated flame retardant having a temperature of 5% mass loss from 350 DEG C to 500 DEG C and a retention mass at 650 DEG C from 2% to 50% by weight, where the 5% mass loss and the retention mass at 650 DEG C are measured according to thermogravimetric analysis; and antimony trioxide, wherein the polymer composition has a molar ratio of antimony (Sb) to bromine (Br) (Sb: Br molar ratio) of greater than 0.0 to 0.35. A coated conductor may be formed using the polymer composition. 本发明涉及一种聚合物组合物，该聚合物组合物包含：硅烷官能化的聚烯烃；溴化阻燃剂，该溴化阻燃剂具有从350℃至500℃的5％质量损失的温度和从2重量％至50重量％的650℃下的保留质量，其中该5％质量损失和650℃下的保留质量根据热重量分析来测量；和三氧化锑，其中该聚合物组合物具有大于0.0至0.35的锑(Sb)与溴(Br)摩尔比(Sb∶Br摩尔比)。可使用该聚合物组合物形成涂覆导体。
