摘要：
Constrained geometry metallocene catalysts can be used to synthesize polyolefins with narrow molecular weight distributions and significant degrees of long chain branching. These polymers have excellent mechanical properties combined with good processability (good shear thinning, delayed melt fracture, and improved melt strength). The bivariate distribution of molecular weight and frequency of long chain branching has been solved analytically for a continuous stirred tank reactor operating at steady-state. Numerical solutions of the population balance equations and Monte Carlo simulations are in perfect agreement with the analytical solution.
