M. Debowski et al., GLASS-TRANSITION TEMPERATURES OF POLYURETHANE-UREA ELASTOMERS BASED ON N,N'-ETHYLENETHIOUREA AND N,N'-ETHYLENEUREA AS CHAIN EXTENDERS, Journal of thermal analysis, 43(1), 1995, pp. 219-225
Glass transition temperatures of polyurethane-urea elastomers (PU) bas
ed on two urea derivatives, have been investigated with differential s
canning calorimetry (DSC) and dynamic mechanical thermal analysis (DMT
A) methods. The DMTA measurements have been proved as more useful to d
etermine an optimal annealing time and to controlling polyurethane-ure
a synthesis then the DSC analysis.
