| 摘要 |
New polynuclear aromatic diamines, such as 2,2'-di-(p-aminophenoxy)-biphenyl, a process for their manufacture and their use as polycondensation components for the manufacture of polyamide, polyamide-imide and polyimide polymers are described. The polymers obtained with the aromatic diamines according to the invention are readily soluble and can also be processed from the melt and are distinguished by good thermal, electrical and/or mechanical properties.
