“…To improve the solubility of PPO in the polysiloxane base, the molecular structure was modified by introducing a tert-butyl substituent. The introduction of a branched alkyl radical does not significantly affect the spectral-luminescent properties of the activator, but at the same time increases its solubility in non-polar solvents and polymer mediapolystyreneand polysiloxanes [7,8]. An increase in the solubility of the activator made it possible to increase its concentration in the scintillation composition up to 2 wt.%, which should have a favorable effect on its scintillation characteristics (Fig.…”

Polysiloxane-based scintillators with different contant of aromatic chromophore groups have been obtained. 2,5-diphenyloxazole and its alkyl derivative were used as activators. The optical and scintillation properties of the obtained polysiloxane scintillators have been studied, and their radiation resistance has been determined. The prospect of using the material in fields with high dose loads is estimated.

“…4ʹʹ-трис-трет-бутил-1,1ʹ:4ʹ,1ʹʹ-терфеніл бутильних замісників. Введення розгалуженого алкільного замісника істотно не впливає на спектрально-люмінесцентні властивості активатора, але при цьому підвищує його розчинність у неполярних розчинниках і полімерних середовищах типу полістиролу та полісилоксанів[8,9]. Незаміщений п-терфеніл нам не вдалося ввести у сцинтиляційну композицію в кількості більше, ніж 0,05 мас.…”

One of the problems in creating a radiation-hard scintillation composition on a polysiloxane base is the search for a radiation-hard activator capable of dissolving in such a base in sufficient quantity. In this work, in order to improve the solubility of p-terphenyl molecules in a polysiloxane base, its structure was modified with tert-butyl substituents. The obtained alkyl derivative of p-terphenyl was used as an activator of polysiloxane-based scintillators. The optical and scintillation properties of the obtained polysiloxane-based scintillators were studied, and their radiation hardness was determined.
