Summary
The work of this thesis is part of a larger effort to develop a computer-based simulation package to assist in understanding urethane-forming thermoset polymerizations and to assist in developing improved formulations. One of the challenges of simulating polymerization is the prediction of the large number of products and intermediates formed during polymerization reactions. The goal of this work is to estimate the viscosities of urethane- forming reactions; accurate viscosity information is critical as an intermediate step to predict how successful a foam formulation would be and to ultimately estimate the final physical properties of the foam. Based on experimental viscosity data collected from single materials and binary system mixtures, a group contribution method was introduced to estimate viscosities of a range of polyol oligomers and urethane polymers at temperatures from 25 to 150ðC. Use of mixture rules then extends the estimation method to multi-component reacting systems. Mixture viscosity data were used to determine the Gibbs free energy (G) in the Grundberg-Nissan equation which can be used to estimate mixture viscosities with correction for some non- idealities. The resulting model is able to accurately predict mixture viscosities based on binary interaction. Chapter 2 summarizes the group contribution equations, methodology, and experimental data used to verify the method. Chapter 2 summarizes the Chapter 2 group contribution method along with a method developed for heat capacities and presents them in a textbook format with a focus on common features of the group contribution approaches and examples on how to use the methods
