Abstract
Çapraz baglama seviyesinde tam kontrol ve nihai ürünün sabit özellikleri açisindan ayni sekilde yüksek seviyede tekrar üretilebilirlik saglayan, karboksi gruplari içeren çapraz baglanmis polisakaridler hazirlamak için bir islemdir. Islem, susuz aprotik çözücü içinde karboksi gruplarinin aktiflestirilmesini ve daha sonra bir poliamin ile tepkimeye sokulmasini içerir. Elde edilen çapraz baglanmis polisakarid bes hidroksit grubunun kükürtlestirilmesi islemine tabi tutulabilir.
