Abstract

Det beskrives en permeabllltetsselektlv podingspolymer som blir dannet ved omdanning til intermedlatreaktlve steder av en del av cyanogruppene l en ryggradspolymer som Inneholder (a) enheter, og poding av polyalkylen- oksldpolymerkjedene til ryggradspolymeren gjennom de reaktlve stedene. Enten kan ryggradspolymeren av en polymerharplks eller en permeabllltetsselektlv polymermembran bil podet. Kår det blir anvendt en harpiks, blir den dannet til en permeabllltetsselektlv polymermembran ved å anvende kjente metoder. Den resulterende permeabllltetsselektlve membranen kan bil dannet til hule fibre eller flate ark for Innkapsling av levende celler. De Innkapslede cellene blir deretter Implantert i en pasient som har behov for biologisk aktive faktorer fremstilt av cellene. Den permeablll- tetsselektlve podingspolymermembranen utviser god molekylær diffusjon med minimal proteinadsorpsjon.
