English College of Education for Pure Sciences Discusses Master's Thesis Titled: "Study of Physical Variables of Polypropylene Glycol of Different Molecular Weights"
A master's thesis titled "Study of Physical Variables of Polypropylene Glycol of Different Molecular Weights" by researcher Salwa Hatem Shukr was discussed at the College of Education for Pure Sciences.
The thesis addressed the study of the thermal and physical behavior of PPG polymers with various molecular weights using theoretical models and accurate numerical simulations, which showed good agreement with experimental results. The results indicated that low molecular weight polymers are more flexible and more affected by temperatures, while high molecular weight polymers enjoy greater thermal and structural stability.
It was also observed that the gradient energy coefficient and surface tension decrease with rising temperature, and their behavior varies according to the molecular chain length, confirming the efficiency of the adopted models in characterizing thermal and surface properties and supporting industrial applications.
