The radiation and thermal stability of optical characteristics of polystyrene scintillators modified by plasticizers based on derivatives of naphthalene, ditolylmethylene, diphenylene oxide, ether of phthalic acid and oligo-phenyl-methyl-siloxanes were studied. It was shown that structure and size of plasticizer molecule make a definite influence on scintillators characteristics of operational conditions stability.
