| 摘要 |
<p>This invention concerns a composition that is capable of chemically bonding, within itself, both large, or small quantities of hydrogen. …<??>Once the composition, formed by a compound made of an unsaturated polymer, substantially a butadienic polymer and of a catalyst, is inserted into a cable containing opticalfibres, then the compound protects these from the effects of the hydrogen derived from any source whatsoever, also included are those opticalfibre cables, and opticalfibres cable-components which incorporate the compound in question.</p> |
