the range of 345–366 nm, showing a very light color characteristic.
The bulky biphenylene phosphinate pendant, which separated the
chromophoric groups and interrupted the intramolecular conju-
gation, provided a highly irregular structure for the resulting
polyamides, and might be responsible for the light color charac-
teristic [40–42].

The results of atomic oxygen resistance of polyamides 5 are
shown in Fig. 8. The weight loss of polyamides 5 under oxygen
plasma was compared with that of polyimide Kapton and poly-
amide 6. To distinguish the effect between thermal-induced and
oxygen plasma-induced decomposition, the plasma chamber was
initially operated under a pure argon atmosphere at a flow rate of
20 sccm. Less than 1 wt% loss was observed for all polymers after
6 min exposure, indicating that the thermal-induced decomposi-
tion is negligible. When oxygen at a flow rate of 5 sccm was
introduced, Kapton and polyamides 6 decomposed rapidly and

decomposition occurred. In contrast, polyamides 5 displayed lower
weight loss, and thus much better oxygen plasma resistance than
Kapton and polyamide 6. Besides, the low-color characteristic of
polyamide 5 resulted in low solar absorptivity in the low Earth
orbital. The preliminary results demonstrate that polyamides 5 are
promising materials for potential space applications.

4. Conclusions
An inexpensive route to prepare (1)-derivative via nucleophilic
substitution was revealed. It is found that the molar ratio of
potassium carbonate-to-(1) is crucial to the product of the nucleo-
philic substitution. When the molar ratio of is 2.10 (typical value of
nucleophilic substitution), according to 1H and Mass spectra, a two-
stage cleavage of (2) was observed, and the 1,4-bis(4-nitrophenoxy)
benzene is the final product. When the molar ratio was reduced to
1.05, the nucleophilic substitution can be carried out successfully
without alkaline hydrolysis. This finding will provide an economic
route for a successful synthesis of (1)-derivatives via nucleophilic
substitution. The bulky biphenylene phosphinate pendant in
polyamide 5 is responsible not only for the improved solubility, the
low-color characteristic, but also for the good oxygen plasma
resistance. The combination of light color, flexibility, high molecular
weight, high glass transition temperature, high thermal stability,
improved organo-solubility, and good oxygen plasma resistance
makes polyamides 5 promising polymers.
