Liquid phase adsorption of organic amines on sulphonated styrene-divinylbenzene copolymers

, 1979
Sorption of organic amines from various solvents on standard and macroporous sulphonated styrene-divinylbenzene copolymers has been studied. The amount sorbed depends above all on the molecular mass (size) of sorbate, but its chemical affinity (basicity)

Effect of SBS Copolymer Molecular Structure on the Long‐Term Aging and Resilience of Asphalt Binders: A Multiscale Morphological Study

Macromolecular Materials and Engineering, Volume 311, Issue 8, August 2026.
Vinyl content governs the long‐term ageing resistance of SBS‐modified bitumen. Multiscale AFM, FM, SEM, and FTIR analyses show that low‐vinyl SBS copolymers (L‐SBS, B‐SBS) undergo pronounced bee‐phase growth, stiffening, and network fragmentation after PAV ageing, whereas high‐vinyl variants (HV‐SBS, DB‐SB) retain their morphology and chemistry ...
