Analysis of Terminal Structure of Synthetic Polymer by Use of Matrix-Assisted Laser Desorption Ionization Mass Spectrometry (MALDI-MS) Equipment



The properties of synthetic polymer are significantly affected by its terminal structure. Matrix-assisted laser desorption ionization mass spectrometry (MALDI-MS) equipment is a device capable of analyzing the terminal structure. An analysis of the lowmolecular weight components directly or indirectly extracted makes it possible to obtain information on the terminal and study a correlation with the physical properties.

Example of analysis

Mass spectrum of nylon 66

Ax: Nylon 66
By: Nylon 66 having both terminals being hexamethylene diamine
Cz: Nylon 66 having both terminals being adipic acid

The structure of 3 types of nylon having different terminal structures was estimated by analyzing the m/z value of the peaks detected.
