Oligomer absorption and calculation of the maximum content of dispersed particles in dispersed filled polymer composites
The paper presents a method for determining the maximum content of dispersed filler (φ<sub>m</sub>) in dispersed-filled polymer composite materials (DFPCM) by oligomer-absorption. For the first time, data on the values of the parameter φ<sub>m</sub> in the DNPCM obtained from oligomer- (<i>Y</i>, g/100 g) and oil absorption method (<i>X</i>, g/100 g) are presented. The dependences of the parameter φ<sub>m</sub> on the particles size for fillers with a particle size from 50nm to 250 microns are presented. It is shown, that the main advantage of using the new method for determining the parameter φ<sub>m</sub> is the possibility to bring the dispersed system closer to the real conditions for DFPCM production and thus, to increase the reliability of the results.
