Abstract：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, <sub>13C NMR, and Py-GC/MS. The results show that the polymers are SBS and polyisobutylene.
