The radiolysis of polycarbonate presents similarities to that of aromatic polysulphones [383, 384]. It undergoes main-chain scission with a G value of 0.09 under vacuum and 0.14 in an oxygen atmosphere. The gases evolved are carbon monoxide, carbon dioxide, hydrogen and methane. The G values are, respectively, 3.6 x 10 1,1.9 x 10 1, 1.3 x 10 2 and 1.3 x 10-3. Since G(CO + C02) is larger than the G value for chain scission, cage recombination of the macroradicals is supposed to occur.
