Abstract: 

A method for modifying activator molecules is described. A series of plastic scintillators with the different content of the activator 2.5-bis(4-(tert-butyl)phenyl)oxazole (DtBuPPO) up to 40.0 wt. % has been obtained. Their scintillation characteristics and physico-mechanical properties were studied. The possibility of using the new scintillators for n/γ-discrimination tasks is shown.
