To det. the copolymer compn., in this article, a robust algorithm is proposed for the compositional assignment and for the estn. of the relative abundance of each species present in copolymer mass spectra. Our homemade software enables the accurate calcn. of the compositional drift, i.e., the variation of copolymer compn. with the polymer chain lengths. Furthermore, we introduce a novel copolymer quantity, namely, the polydispersity (also called as dispersity) ratio (PDR) of the comonomers, and establish a characteristic relationship between the shape of the compn. drift curves and the PDR values. This relation allows, for instance, a quick visual recognition of the presence of diblocks in a triblock copolymer by means of mass spectrometry. Our approach is demonstrated by the anal. of various poloxamers, i.e., polyethylene oxide (PEO)​-​polypropylene oxide (PPO) block copolymers up to the av. mol. wt. of approx. 4000 g​/mol. The detd. no.-​av. mol. wts. and the ethylene oxide contents were also confirmed by NMR spectroscopy. Dynamic light scattering expts. revealed that small variations in the copolymer compn. significantly affect the properties of the copolymer.}, year = {2021}, eissn = {1520-5835}, pages = {9984-9991}, orcid-numbers = {Nagy, Tibor/0000-0001-8568-914X; Hashimov, Mahir/0000-0003-1713-4366} } @misc{MTMT:34158854, title = {European Meeting on Fire Retardant Polymeric Materials.
