However, when the polymer chain length is very large, such a direct integration of polymer population balance equations can be computationally demanding. In this paper, the method of finite molecular weight moments is applied to the calculation of polymer chain length distribution in a batch free ...

On the basis of these data, an empirical equation has been derived giving the molecular weight of petroleum products as a function of mean boiling point, density, and refractive index; this equation can be recommended for engineering calculations....
Problems associated wtih poor baseline recovery between the end of the polymer chromatogram and the beginning of the solvent impurity peaks are discussed, and an approach for accurate calculation of molecular weight averages of polymers is described. Polystyrene SRM 706, where the presence of low ...
Molecular weight distributions for the polymer produced in a cascade of well-stirred reactors are constructed using the Mathematica software package for symbol mathematical operations. It is shown that the rate of chain transfer to polymer affects the distributions of macromolecules over the degree of ...
