Аннотация: Using methods of IR spectroscopy (Fourier infrared spectrometer; PerkinElmer) and gel permeation chromatography (Agilent 1200; Agilent Technologies), we studied the microstructure and molecular characteristics of four types of diene oligomer (DO) of different functionality. The dynamic viscosity, η, of DOs was measured on a rotary viscometer (LVDV-II+ Pro; Brookfield). A comparative analysis of the obtained results makes it possible to predict the dispersion and the plasticising effect of DOs in polymer-oligomer composites. The temperature dependences of η for different DOs differ in the temperature range 20-60°C; at temperatures of 80°C and above, the values of η are practically identical, i.e. their processing properties are the same, and the replacement of one DO with another will not lead to any need to alter the processing regime of the composites. © 2018, Smithers Rapra.
