InitDecaytor 0.4.4

Simulation of the thermal decomposition of free-radical initiators

InitDecaytor

Thermal decomposition of free-radical initiators

The purpose of this program is to simulate the thermal decomposition of free radical initiators based on reported kinetic data and a set of (virtual) experimental parameters, such as the concentration and temperature.

Currently, multiple charges of a variety of radical initiators are supported at a constant temperature. Alternatively, a temperature profile can be imported from the Huber SpyControl software. The end-time of the experiment can be visualized based on a desired threshold of initiator relative to its maximum concentration.

Developed on a fresh python install (v3.13) with the most recent package versions in June 2025. In case of issues, please consider updating your packages.

How to get started?

Install InitDecaytor:

pip install InitDecaytor

or upgrade if you've installed a previous version before:

pip install --upgrade InitDecaytor

Create a python script, for example GUI.py, containing the following code:

import InitDecaytor

if __name__ == '__main__':
    app = InitDecaytor.GUI()
    app.run(debug=True)

Finally, run the script:

python GUI.py
