Grafting one type polymer onto a different polymer type may yield a combbranched 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 suc
## Abstract Gel permeation chromatograms of a hinderedβphenolic, branched condensation polymer display pronounced bimodality at high conversion. The true molecular weight distributions, obtained by means of a GPC calibration curve based on narrowβdistribution fractions, exhibit corresponding anomal
