Simulated space environment effects on the optical properties of poly(arylene ethers)Results are reported from a study of the stability of poly(arylene ethers) formed in a reaction of 1,3 -bis(4-chlorobenzoyl)benzene and various bisphenols after experiencing long-term exposure to space conditions. Transparent poly(arylene ethers) films were subjected to separate electron and UV bombardments, as were polysulfone and Kapton films for comparisons. The order of exposure to the two types of radiation was reversed for two sample populations. The optical properties and glass transition temperatures of the samples were determined after irradiation. The poly(arylene ethers) films exhibited good resistance to the electron radiation but suffered severe degradation in the UV environment. The loss of optical transmissivity was proportional to the UV radiation dose.
