Abstract:
The preliminary results about the influence of the sulphur concentration vulcanized during the polymerization process into polymeric rubber (polybutadiene) (1.1% - 2.8% sulphur in rubber) was studied by SANS (small-angle neutron scattering) with YuMO spectrometer at IBR-2 pulsed reactor of JINR, Dubna.
The experiment was performed at room temperature. It was shown that the correlation peak corresponds to a 130 Е size of inhomogeneity and presents a weak dependence from concentration of sulphur.
