Title Monte-Carlo simulation of ester exchange reactions in PET/PEN blends
Date 17.12.2013
Number 41102
Abstract Monte–Carlo kinetic simulations are performed to study exchange reactions in PET/PEN blends. Chain distribution of the blend is simulated at various mixing conditions. The average length of PET and PEN repeating units decreases with increasing exchange reactions. Derivative of heat flow is modeled at Tg region during mixing. Two peaks are observed on the derivative of heat flow curve at the early stages of mixing, indicating formation of an immiscible blend. With increasing mixing time, miscibility between two phases increasea and the peaks converge toward each other and finally form a single peak. The Monte–Carlo simulation results are in fine agreement with experimental data obtained from different systems.
