A kinetic model for thermal degradation in polymers with specific application to proteins

Abstract:

We present a novel method for calculating degradation kinetics in polymers. Our calculations directly use the dissociation energy of chemical bonds in a polymer chain to predict weight loss as a function of time and temperature in an Arrhenius-type activation function. The novelty lies in quantifying the thermal energy term for skeletal bonds in the chain backbone in the activation function that initiates the bond fission process and that also quantifies the pre-exponential rate term. Our met...
