Popis:	4′-N-(Benzo-15-crown-5)maleimide (I) was prepared by dehydration of the corresponding maleamic acid (IV). The complexation constant, K=0.07 L mol−1, between I and ∝-methylstyrene (∝-MeSt) was determined by modified Benesi-Hildebrand NME method. The copolymerization of ∝-MeSt with homopolymerizable I at different monomer-to-monomer ratios in the feed was performed up to high conversion in Calvet microcalorimeter. It was found that in the copolymerization of ∝-MeSt with an excess of I, the alternating copolymerization precedes the homopolymerization. The mixture of alternating copolymer and homopolymer of I has a single Tg, thus indicating the miscibility on molecular level.
