| 摘要 |
A polymer derived from a mono-olefin is stabilized with carbon black activated by the addition of oxygen, sulphur or selenium to the surface of the carbon black particles. Specified polymers are those derived from ethylene, propylene, isobutylene, butene, methyl butene, methyl pentene, dimethyl pentene, dodecene and/or styrene. The activated carbon may be obtained by admixture of carbon black with sulphur or selenium, or by pyrolysing carbon black with oxygen, sulphur or selenium. Unactivated carbon black also may be present. |
