摘要: This is the first of two papers presenting a new mathematical method for modeling bivariate distributions polymer properties. It based on transformation infinite mass balances describing evolution two-dimensional distribution using 2D probability generating functions (pgf). A key step this inversion transforms. In work, numerical methods pgfs are developed and carefully validated. The accuracy obtained with both was very satisfactory. formulas simple easy to implement. copolymerization example used show complete procedure from derivation pgf recovery molecular weight distribution.
