Thin films of four experimental poly(arylene ether)s of similar chemical structure were exposed to 1 MeV electrons while under high vacuum. The films received total exposures of 5 x 107 and 1 x 109 rads at a dose rate of 5 x 107 rads h-1 and a pressure of 2 x 10-7 torr. Films exposed to 5 x 107 rads showed dramatic changes in molecular weight distribution. After exposures of 1 x 109 rads the films were only partially soluble in chloroform and exhibited no detectable changes in the glass transition temperatures. Thin-film tensile properties were also altered by the exposure to electron radiation. The effect of the exposures as determined by various analyses is discussed.
