Evolution of the crosslink structure in the elastomers NR and SBR
An experimental positron annihilation lifetime spectroscopy (PALS), differential scanning calorimetry (DSC) and small angle X-ray scattering (SAXS) study of the effect of the advance of the crosslinking reaction on the free volume in a copolymer of styrene-butadiene and natural rubbers was carried o...
