Abstract A series of polyurethane elastomers (PUEs) derived from three thiacalix [4] arene derivatives (TC4As), namely p-tert-butylthiacalix [4] arene, tetrasodium thiacalix [4] arenetetrasulfonate and thiacalix [4] arenetetrasulfonic acid, as a portion of chain extender in a mixture with glycerol were synthesized. The effects of the chemical structure of TC4As used as chain extenders on the various properties of the prepared PUEs were investigated and compared with PUE extended with only glycerol as chain extender using Fourier ...
