Surface properties of heavy petroleum distillation residues

A series of surface sulphonated macroporous styrene-divinylbenzene (S-DVB) copolymers containing various amounts of -SO,H groups was obtained. Porous structure, surface hydrophilicity and polarity, and sorption properties of these copolymers as well as those of starting S-DVB resin towards some substances which are present in blood were determined. The sorption degree becomes the smaller the higher is the surface polarity. The partially sulphonated copolymers may find an application in hemoperfusion. ZUS AMMENFASSUNG:Eine Reihe oberflachensulfonierter, makroporilser Styrol-Divinylbenzol-Copolymerer mit unterschiedlichen Gehalten an S0,H-Gruppen wurden hergestellt. Sowohl von diesen Copolymeren als auch vom nichtsulfonierten Copolymeren wurden Porenstruktur, Oberflachenhydrophilie und -polaritat sowie das Sorptionsverhalten gegeniiber einigen in Blut vorkommenden Substanzen bestimmt. Der Sorptionsgrad wird umso kleiner, je grilI3er die Oberfliichenpolaritat ist . Die teilsulfonierten Polymeren k8nnten eine Anwendung in der Hhoperfusion finden.
