A polymer composition comprising a silane-functionalized polyolefin, a brominated flame retardant having a 5% mass loss temperature of from 300 DEG C to 700 DEG C as measured according to thermogravimetric analysis, and antimony trioxide wherein the brominated flame retardant is polymeric and as measured using gel permeation chromatography, the weight-average molecular weight of the brominated flame retardant is from 1,000 g/mol to 30,000 g/mol. The molar ratio of antimony (Sb) to bromine (Br) (Sb: Br molar ratio) of the polymer composition is from 0.35 to 0.98. 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、溴化阻燃剂和三氧化锑，如根据热重量分析测量的，该溴化阻燃剂的5％质量损失的温度为300℃至700℃，其中该溴化阻燃剂是聚合物的并且如使用凝胶渗透色谱法测量的，该溴化阻燃剂的重均分子量为1,000g/mol至30,000g/mol。该聚合物组合物的锑(Sb)与溴(Br)摩尔比(Sb:Br摩尔比)为0.35至0.98。
