“…Broersen et al. developed a method for the derivatization of polyamide resins with o‐phthalaldehyde before analysis with SEC‐fluorescence detection [125]. While the selectivity of the fluorescence detector renders that it is not applicable to most polymers, it may prove to be interesting for the selective quantification of functional groups after derivatization.…”

Accurate quantification of polymer distributions is one of the main challenges in polymer analysis by liquid chromatography. The response of contemporary detectors is typically influenced by compositional features such as molecular weight, chain composition, end groups, and branching. This renders the accurate quantification of complex polymers of which there are no standards available, extremely challenging. Moreover, any (programmed) change in mobile‐phase composition may further limit the applicability of detection techniques. Current methods often rely on refractive index detection, which is not accurate when dealing with complex samples as the refractive‐index increment is often unknown. We review current and emerging detection methods in liquid chromatography with the aim of identifying detectors, which can be applied to the quantitative analysis of complex polymers.

“…The resulting activated acid group can be displaced by using alcohols or amines, resulting in the formation of esters or amides, respectively. Broersen et al described the analysis of primary-amine containing functional polymers by a pre-column derivatization with o-phthalic aldehyde in combination with SEC and fluorescence/UV detection [17]. The work done by Borisov et al [18] focuses on MS applications using derivatization of polymers, including acylation of hydroxy-functional ethoxylates with phthalic anhydrides or 2fluoro-1-methylpyridinium p-toluenesulfonate.…”
