A method of determining the distribution of branching in a polymer is developed employing limiting viscosity numbers (intrinsic viscosity), gel permeation chromatography (GPC), and absolute molecular weight determinations of fractions of the whole polymer. A molecular weight calibration of the GPC c
## Abstract In the present study a population balance approach is described to follow the time evolution of bivariate molecular weightβlong chain branching (MWβLCB) distributions in high pressure low density polyethylene autoclaves. The model formulation is based on a sectional grid method, the soβ
