ABSTRACT: The paper studies oil absorption by polyurethane sorbents synthesized at temperatures of 20, 30, 40, 50, 60 and 70°C that is necessary for the development of physicochemical foundations of the oil absorbents synthesis. It is revealed that the kinetic curves of oil absorption of the obtained sorbents, as well as previously studied industrial polyurethane foams existing in a glassy state, are characterized by the presence of maximum (at 30 min), while increasing the synthesis temperature leads to an increase in oil absorption. The author gives interpretation of obtained patterns, which are confirmed, in particular, by the electron-microscopic study.

KEYWORDS: Polyurethane Foam; Process Temperature; Process Activation Energy; Diffusion of the Blowing Agent
