摘　　要：通过化学分离从改性沥青卷材中分离出高聚物,然后借助于红外光谱、核磁共振碳谱、裂解气相色谱/质谱联用仪对聚合物的结构进行了分析。The waterproof roller sheet of modified asphaltum is extensively used in many waterproof constructions. The modified asphaltum by polymer is of good performance, such as cold-resistant, high intension etc. In the present paper, the modifying polymer was seperated from the waterproof membrane of modified asphaltum. The structure of the modifying polymer was identified by IR, ^13C NMR, and Py-GC/MS. The results show that the polymers are SBS and polyisobutylene.

关 键 词：改性沥青防水卷材 红外 核磁 裂解气相色谱质谱联用
