We have reported the first attempt with dynamic nuclear polarization (DNP) and contrast variation small-angle neutron scattering (SANS) experiments on model mixtures for industrial tyres conducted at the MLF of J-PARC. We performed time-of-flight SANS (TOF-SANS) experiments, employing neutrons with a wide range, which causes imperfect neutron polarization and variations in the coherent and incoherent scattering lengths. By carefully eliminating the effect of imperfect neutron polarization, separation of the partial scattering functions was successfully demonstrated for the ternary system styrene-butadiene-rubber/silica/carbon.
