1. Yоur cоmpаny stаndаrds mandate that the pоlydispersity index for your new polymer processing procedure yield a polydispersity index of less than or equal to 1.15. Your polymer processing ends with 3 fractions, labeled G, H, & I in the table below with the breakdown of different size chains within your new polymer sample. Does your new fabrication method meet that standard? Show all your work and justify your answer (describe the measurement you are comparing and why).
