Abstract:
The invention relates to a method for producing sulphated cellulose esters which can be used for micro-encapsulation. The invention also relates to corresponding micro-capsules consisting of sulphated cellulose esters and cationic polymers. Said micro-capsules can be used as medicaments, in particular for implantation or injection.
