Abstract AR
تمت دراسة ذائبية بولي ستايرين (PS) مع بولي ميثيل ميثاكريليت (PMMA) في محلول مخفف باستخدام فحص اللزوجة، حيث تمت دراسة خلطات من PS/PMMA مكونة من نسب 0.1/0.9, 0.3/0.7, 0.5/0.5, 0.7/0.3 و 0.9/0.1 عند درجة حرارة 20 و 30 م˚ في مذيب التتراهايدروفيوران (THF).
و قد تم تحديد اللزوجة الحقيقة و عامل التفاعل اللزوجي للنظام المزدوج (مذيب / بوليمر) و النظام الثلاثي (مذيب / بوليمر1 / بوليمر2).
و تم تقدير درجة التكاملية بين أنظمة البوليمر هذه اعتمادا على المحددات الستة التالية : 1) إشارة 2 ∆ [n]) إشارة ∆ b23 3) إشارة µ (4 إشارة ∆ bm (5 إشارة α, و (6 إشارة β.
و اعتمادا على عرف الإشارة المتضمن في هذه المحددات تمت ملاحظة ذائبية جزئية في نظام.
كما وجد ان الذائبية بين بولي ستايرين و بولي ميثيل ميثاكريليت تزداد بازدياد درجة الحرارة من 20 إلى 30م˚ و تقل بالوزن الجزئي للبولي ستايرين.
Abstract EN
Miscibility of Polystyrene (PS) with Poly (methylmethacrylite) was studied in dilute solution by viscometers.
Blends with PS/PMMA composition of 0.1 / 0.9, 0.3 / 0.7, 0.5 / 0.5, 0.7 / 0.3, and 0.9 / 0.1 were studied at 20°C and 30°C in Tetrahydrofuran (THF) solvent.
The intrinsic viscosity and the viscometric interaction parameter have been determined for the binary (solvent / polymer) and ternary (solvent / polymer1 / polymer2) systems.
The degree of compatibility of these polymer systems was estimated on the basis of the following six criteria: (1) the sign of Δ [η].
(2) The sign of Δb23, (3) the sign of μ, (4) the sign of Δ BM, (5) the sign of α, and (6) the sign of β.
Based on sign convention involved in these criteria, partial miscibility was observed in the PS / PMMA system.
Miscibility between PS and PMMA was found to increase with temperature from 20°C to 30°C and decrease with weight fraction of PS.
