    摘要: This invention relates to a roofing or siding membrane comprising a non-woven mat coated with an asphaltic composition containing, in addition to 35-75 wt. % bitumen, a mixture of isotactic and amorphous propylene polymers and between about 0.08 and about 15 wt. % of a functionalized, olefin polymer to provide a non-staining membrane of high tensile strength, low polyolefin content with respect to asphalt, improved compatibility between asphalt and non-functionalized polymers and reduced light end asphalt and polymer exudates. The invention also relates to a method for preparing the membrane.
