Modeling molecular weight distribution of comb‐branched graft copolymers

Grafting one type polymer onto a different polymer type may yield a comb‐branched copolymer. The branching density has a significant effect on its overall molecular weight distribution. A general model is derived to describe the bivariate distribution of molecular weight and branching density for such comb copolymers. The model is applicable for various grafting mechanisms provided the side chains are randomly grafted onto the backbone. The …
