概要	Carboxy-terminated 4-arm star-shaped caprolactone oligomers (Tetra-SA-CLO, Tetra-PA-CLO and Tetra-TCPA-CLO) were synthesized by the reactions of hydroxy-terminated 4-arm star-shaped caprolactone oligomers (Tetra-OH-CLO) having the degree of polymerization per one oligocaprolactone chain, n = 3 and 5 with succinic anhydride, phthalic anhydride and 2,3,4,5-tetrachlorophthalic anhydride, respectively. As a pyridyl-terminated analog, nicotinate-functionalized 4-arm star-shaped caprolactone oligomer (Tetra-NA-CLO) was synthesized by the reaction of Tetra-OH-CLO with nicotinic acid. All mixtures of the carboxy- and pyridyl-terminated analogues became thermoreversible organogels in DMF and nitromethane at around 15 degree C. The 1H-NMR and FT-IR analyses of the mixtures revealed the formation of hydrogen-bonded polymer network. The glass transition and cold crystallization temperatures of the mixtures were higher than the values estimated from those of the single components.
