لقد تم التمكن من الحصول على خلائط DGEBA/Phn بوساطة تقنية الخلط التعاقبي.
و قد تمت دراسة معامل التوصيل الحراري لهذه الخلائط خلال المدى الحراري 303-373˚K، و أظهرت النتائج زيادة في قيم معامل التوصيل الحراري عند زيادة النسبة الوزنية للنوفولاك (Phn)، و رصدت زيادة في معامل التوصيل الحراري عند درجات الحرارة العالية نتيجة زيادة الحركة الجزيئية الداخلية.
كذلك تمت دراسة الاستقرارية الحرارية لخلائط DGEBA/Phn باستخدام تقنية التحليل الحراري التفاضلي (DTA) و تقنية (TGA) و قد بينت النتاج أن درجة حرارة التحول الزجاجي و نسبة متبقي الفحم تزداد بزيادة النسبة الوزنية للنوفولاك (Phn)، مما يشير إلى أن النوفولاك قد حسن من الاستقرارية الحرارية للخلائط.

The DGEBA / Phn blends were formulated by a sequential mixing process.
The thermal conductivity (k) of the blends has been measured as a function of temperature over the range 303–373K°.
The results show that the values of k increase with increasing Phn weight fraction.
It also considers an increase in the effective thermal conductivity at high temperatures due to increasing the intermolecular vibrations.
Thermal stability was investigated by differential thermal analysis (DTA) and thermo-gravimetric analysis (TGA) techniques.
Both glass transition temperature (TG) and char yields of the blends increase with increasing Phn weight fraction.
The novolac enhances the thermal stability of DGEBA.The DGEBA / Phn blends were formulated by a sequential mixing process.
