摘要：
The multi-block structure of olefin block copolymers (OBCs) leads to their unique properties, in contrast to those of traditional polyolefin elastomers. In this work, the detailed bivariate distribution of molecular weight and chemical composition (MWD x CCD) of OBCs is examined using Monte Carlo simulation. The effects of polymerization parameters on the bivariate MWD x CCD are also studied and reported for the first time. This model can be used as a tool to describe how to produce OBCs with desired microstructures by manipulating the polymerization conditions.
