| Abstract: | Based on the characteristics of an actual industrial process of polyester , a mathematical model of esterification have been built. In this model ,some measured process parameters have been used as input and the quality-indices such as degree of esterification,concentration of carboxyl end groups,saponification value, DEG content as output.Thus it can provide the operator with timely product information. |
