The way of life of amphibians and reptiles, in contrast to that of birds and mammals, is based on low energy flow. Many of the morphological and physiological characteristics of ectothermal tetrapods that are normally ...
Properties of segmented polyether poly(urethaneureas) based of 2,4-toluene diisocyanate. 2. Infrared and mechanical Studies
(American Chemical Society: Macromolecules, 1980-01)
: IR spectra of two series of polyether poly(urethaneureas) based on 2,4-toluene diisocyanate, ethylenediamine, and either 1000 or 2000 molecular weight poly(tetramethy1ene oxide) were examined first to elucidate the state ...
