  1. 1.

    The optical absorption spectra of a number of triplet excited aromatic molecules in polystyrene were investigated by the method of pulsed radiolysis. For molecules with known coefficients of extinction of triplet-triplet absorption the radiation yields of the triplet states of the additive were determined.

  2. 2.

    The quenching of triplet molecules by radiolysis products as a result of nonhomogeneous reactions in spurs was established. The lifetime of spurs in polystyrene is∼10−3 sec.
