A series of bis(ether anhydride)s has been synthesized from very
bulky
bisphenols. Poly(ether imide)s have been synthesized from these
bis(ether
anhydride)s and two diamines in order to provide a series of
poly(ether
imide)s with bulky main-chain units. The polymers have been
characterized
in terms of molecular weight, solubility, glass-transition
temperature and
thermal stability in order to identify a series of high-performance
polymers which are processable and potentially useful for
applications
which require soluble poly(ether imide)s for fabrication into, for
example, gas separation membranes.
一系列的双(醚酸酐)是从非常庞大的双酚合成的。聚(醚酰亚胺)是通过这些双(醚酸酐)和两种二胺合成的,目的是提供一系列具有大型主链单元的聚(醚酰亚胺)。为了识别一系列可加工的高性能聚合物,这些聚合物在分子量、溶解性、玻璃转变温度和热稳定性方面进行了表征,可能对需要可溶性聚(醚酰亚胺)用于制造气体分离膜等应用非常有用。
