## Abstract SEC separates complex branched polymers by hydrodynamic volume, rather than by molecular weight or branching characteristics. Equations relating the response of different types of detectors are derived including band broadening, by defining a distribution function __Nβ²__(__M__,__V__~h~)

Branched polymers are among the most important polymers, ranging from polyolefins to polysaccharides. Branching plays a key role in the chain dynamics. It is thus very important for application properties such as mechanical and adhesive properties and digestibility. It also plays a key role in visco
## Abstract The object of this study is to develop multidetector sizeβexclusion chromatography (SEC) methods to determine the number of arms per molecule across the molecular size distribution of starβbranched polymers. An empirical fit between the intrinsic viscosity molecular contraction factor _
