Pyrolysis-Liquid Chromatography for the Analysis of Acrylic Resins.

The determination of the chemical composition distribution of acrylic resins is not straightforward. Pyrolysis-gas chromatography (py-GC) analyses of acrylic resins can yield problems in the recovery of the hydroxyl and acid functional fragments that form. To overcome these problems pyrolysis-liquid chromatography (py-LC) can be performed. This article describes how the validation and quantification of hydroxyl acrylate-, hydroxyl methacrylate-, hydroxyl propylacrylate-, and hydroxyl propylmethacrylate resins by py-LC is performed. Furthermore, off-line size-exclusion chromatography (SEC) coupled to py-LC is performed to determine the chemical composition distribution over the molecular weight distribution of a core-shell waterborne acrylic resin.
