摘　　要：采用阻燃剂苯氧基四溴双酚A聚碳酸酯齐聚物对聚碳酸酯(PC)进行改性,研究了阻燃剂含量对PC力学性能、阻燃性能和热稳定性的影响。结果表明:随着阻燃剂含量的增加,PC复合材料的阻燃等级、氧指数均有显著提高;TGA曲线显示,阻燃剂的加入使PC复合材料热稳定性能明显提高,起始失重温度和最大热失重速率温度均向高温移动,且550℃下的残留率和最终的残留率均明显增多;同时,PC复合材料的拉伸强度、弯曲强度随阻燃剂含量的增加而提高,但冲击强度逐渐降低。Polycarbonate（PC） was modified by flame retardant carbonate oligomer of tetrabromobisphenol A.The effects of flame retardant content on mechanical property,flame-retarded property and thermal stability of PC were studied.The results show that：with the increase of flame retardant content,the flame retarding grade and the OI value of PC composite increase obviously;the addition of flame retardant not only improves the thermal stability of PC,but also increases its initial weight loss temperature and maximum weight loss velocity temperature,and the residual carbon content at 550℃ and final residual carbon content increase obviously;meanwhile,with the increase of flame retardant content,the tensile strength and flexural strength of PC composite increase,and the impact strength decreases.
