Abstract AR
تم في هذه الدراسة قياس الكثافة للمحلول المائي لبوليمر الكحول الفينايلي ذو الوزن الجزيئي (125 kg.
mol-1) في مدى من درجات الحرارة 298.15-328.15 كلفن.
و من هذه القيم تم حسام الحجوم لهذه المخاليط ثنائية المكون و وجد أن الحجوم تعتمد خطيا إلى على مولالية المذاب (PVA) و من هذه الاعتمادية تم حساب الحجم المولاري الجزئي المحدد عند التخفيف إلى ما لانهاية (V2,0) و لوحظ أن هذا الحجم لا يعتمد الى تغير التركيز لكنه يزداد قليلا بزيادة درجة الحرارة.
تم حساب معامل التمدد الحراري (α1.2) في درجة حرارة 298.16 كلفن و لوحظ أن قيمة (α1.2) للمحلول المائي لبوليمر الكحول الفينايلي هي أكبر من قيمة (αo1) للماء النقي.
Abstract EN
The densities of aqueous solution of polyvinyl alcohol with molecular weight (125kg.mol-1) have been determined over temperature range298.15-328.15K.From these data, the volumes for the binary mixtures studied here were calculated.
The volumes have been found linearly dependent on the solute molality (PVA), from this dependence, the partial molar volumes at infinite dilution (V2,0 ) were determined and it was found that the (V2,0 ) concentration independent and slightly increase with increasing temperature.
The thermal expansion coefficient (α1,2 ) of aqueous solution of (PVA) at 298.15K was calculated and it was found that the values of (α 1,2 ) were higher than the value ( α1˚) of pure water.
