摘要
A model is developed to predict rates of undesirable reactions in the low-moisture, high-temperature finishing stage of nylon 66 production. The model contains 56 unknown parameters and initial conditions, which are ranked based on their influence on model predictions, correlation with other parameters and uncertainty in their initial guesses. A mean-square-error criterion is used to determine that 43 of 56 parameters should be estimated. The proposed model, which describes the effect of melt-phase water concentration on degradation, matches the data well with typical errors of 6.1 and 2.
