| 摘要 |
<p>Bitumen-containing compositions comprising bitumen and a minor proportion by weight (e.g. 5 to 25 wt%) of a polymer having one or more neutralised anionic groups covalently bonded thereto, e.g. a zinc neutralised sulphonated EPDM. These compositions have good resistance to creep as well as good elastic properties and may be used for roofing.</p> |
