    • The low PDI values of the polymers relative to the apparent broadness of the GPC RI traces are due to limitations of the GPC-MALLS system which uses light scattering data to calculate the Mw and PDI. This technique is generally considered to be very accurate, but unfortunately the high molecular weight of the star polymers being analyzed generates a very intense light scattering (LS) signal which can mask the LS signal of lower molecular weight polymers and hence underestimate the PDI
