Abstract
A flexible method for characterizing polymer components and the use of the same in general purpose polymer process simulation software has been developed. In this method and software apparatus, polymer molecules are defined in terms of their segments or structural units. In addition, a set of component attributes is associated with each polymer component. The component attributes are used to track information on polymer molecular structure, chemical composition and product properties, such as molecular weight averages, average copolymer composition, particle size distribution, etc. This methodology is used in a consistent manner by all key elements of simulation software, such as thermo-physical property calculations and polymerization kinetics.
