Two different sample, of synthetic rubber (GR–S) were fractionated by the "coacervate" method of Duclaux and his coworkers. This method is some-what analogous to fractional extraction, with this difference that the polymer in the form of a viscous liquid instead of a solid phase. One sample was refractionated into 35 subfractions. The molecular weight distribution curves show a sharp peak in the region of 40,000. The results are comparable with those of fractional precipitation.

Weight Distributions

Abstract Synthetic rubber of different species, types, and degrees of mastication were used to examine the general validity of the proposed relationship between mechanical relaxation spectra in the rubbery region and molecular weight distribution. Results show that the proposed relationship can be well used to discuss quantitatively the role of molecular weight distribution in the theoretical behavior of a raw rubber while being processed.
