What is it about?
Longstanding theories predict the size of linear polymer molecules in solution as a function of molecular weight. Dendritic polymers are a newer, highly branched polymer architecture where the size as a function of molecular weight is not as well understood. We have used diffusion coefficients from Pulse-Field-Gradient NMR to determine molecular radii for both types of polymers to begin to establish a better understanding of the properties of dendritic polymers.

Why is it important?
This is the first comparison of molecular radii from linear and dendritic polymers using PFG-NMR.
Perspectives
This publication is a basic and fundamental study using PFG-NMR that can be used to establish the applicability of this technique in polymer science. This publication also represents the work of numerous students over several years at different institutions - Seton Hall University and Virginia Military Institute.
