Synthesis and Photo-Chemically Induced Dynamic Nuclear Polarization(photo-CIDNP)Study of Monodisperse Photoinitiator Endlabelled Polystyrene

摘要

The study of polymer reaction kinetics depends heavily on the chemical and physical properties of the chain end.However there are several difficulties in systematically studying the chain-end of a polymer.In free radical polymerizations,large distributions of chain lengths make study of chain ends only an aggregate or average of the properties of all chainlengths,obscuring the dependence of chainlength on the measured property.
