Abstract AR
تم في هذا البحـث دراسـة تـأثیر أشـعة كامـا علـى اللزوجـة المختزلـة و الذاتیـة و ثابـت هـویكنز لمحلــول البولیــستیرین فــي مــذیب البنــزین.
إذ تـــم حــساب متوســط الــوزن الجزیئــي للبولیـــستیرین باسـتخدام معادلـة مـارك - هوینـك - سـوكارادا بالاعتمـاد علـى قـیم اللزوجـة الذاتیـة.
كمـا تـم أیـضا دراسة تأثیر درجة الحرارة ضمن المدى الحراري C ْ (25-60) على اللزوجة المختزلـة.
و قـد بینـت النتــائج أن البولیــستیرین یتــرابط عرضــیا بعــد تعرضــه لأشعة كامــا المنبعثــة مــن مــصدر الــسیزیوم 137 Cs في الهواء و یتحلل بزیادة درجة الحرارة.
Abstract EN
In this research the effect of gamma rays had been studied on the reduced viscosity and intrinsic viscosity and Huggins constant of polystyrene (PS) solution in the solvent benzene, by the determination of the average molecular weight of (PS) using Mark - Houwink – Sakurada equation depending on the values of intrinsic viscosity.
The effect of temperature in the range (25-60)C on the reduced viscosity had been studied too.
The results showed that (PS) undergoes crosslinking after irradiation in air with gamma rays emitted from Cs137 source and degradation with increasing temperature.
