Could you please provide the decomposition rate constant of ABVN in VCM, as well as the chain growth rate and chain termination rate in VCM?

I would like to ask about the decomposition rate constant of ABVN in VCM. The decomposition rate constant Kd is required to be determined with an accuracy of 0.1 degrees Celsius; if there is no value for the decomposition rate constant in VCM, one from toluene can be used instead. If you know in which chemical handbook to look, please let me know. Thank you. Also, for VCM, the chain growth rate Kp and the chain termination rate Kt at these temperatures need to be provided in increments of 0.1 degrees Celsius. For the above temperature ranges, just 1 degree Celsius is sufficient; for example, for Kd, Kp, Kt values ranging from 59 degrees Celsius to 60 degrees Celsius.

Does anyone know? Please help. This is mainly because, as PVC polymerization proceeds, Kd, Kp, and Kt in the polymer-rich phase undergo significant changes. I just don’t know at the moment; it would be good to know Kp/(Kt^(1/2)) as well
