Ya. V. Shalaeva,Ju. E. Morozova,Victor V. Syakaev,E. Kh. Kazakova,A. M. Ermakova,Irek R. Nizameev,M. K. Kadirov,Alexander I. Konovalov +7 more
TL;DR: In this paper, a novel water-soluble thermoresponsive oligomers TO1 and TO2 were obtained by reaction of amidoamine tetramethylcalixresorcinarenes (C1) and tetrapentylcalixrecorcinareens (C5) with ethylene glycol diglycidyl ether, which were characterised by 1H and FT-PGSE NMR, FTIR, static light scattering and elemental analysis.
