Method of evaluating a crosslinked vinylpyridine resin

摘要

Provided is a method of evaluating a resin capable of quantitatively evaluating a deterioration degree of the resin with high accuracy and ease. The method includes evaluating the resin based on a shift of a characteristic peak representing a deterioration degree of the resin, the peak being observed in thermal analysis of the resin by a temperature increase, to lower temperatures.

主权项

1. A method of evaluating a resin, the method comprising evaluating the resin based on a shift of a characteristic peak representing a deterioration degree of the resin to lower temperatures, wherein the characteristic peak is observed in thermal analysis of the resin in which a sample of the resin is heated over a temperature range and wherein the resin comprises a resin having a side chain having a nitrogen-containing aromatic ring group and a crosslinking portion.
