Flame retardant additive based on polysiloxane for aromatic polymers |
摘要 |
<p>Novel methods and compositions for improving the flame retardant capabilities of aromatic-based polymers like polycarbonate are disclosed. Other important polymer properties are substantially maintained, such as transparency. One aspect of the invention is directed to a flame retardance additive which comprises a copolymer of an aryl-containing silicone compound and a diorganic polysiloxane compound. In some preferred embodiments, the aryl-containing silicone compound is triphenyl- or diphenyl-based. This invention is also directed to new polymer compositions, which comprise an aromatic-based polymer and the flame retardance additive described above. The polymer compositions can be molded into a variety of articles which have a very useful combination of properties.</p> |
