"Curing of sixteen dihydroxypolybutadiene-based polyurethane compositions was studied by oscillatory rheometry in a broad time interval. The compositions contained chain extender only, consequently, preferably physical crosslinks were formed. The individual samples differed also in the miscibility and reactivity of their components. Studied linear polyurethanes showed the same general curing behaviour as chemically crosslinked systems investigated in previous work. Regardless of type of the crosslinks, miscibility and reactivity of components development of structures responsible for the viscous response precede development of the elastically effective structures which is faster at the beginning. Formation and evolution of the physical and chemical networks, in systems of different miscibility or reactivity are in general identical at least from the small deformation standpoint. Mechanical properties of final product are, however, affected by both the reactivity and miscibility of reacting components."@en . . "Z(MSM0021630501)" .
