The invention relates to a procedure, to a grafted starch derivative produced by this procedure and to its use. In the procedure a starch or starch derivative is graft-copolymerized with a cyclic ester, producing a starch derivative grafted with an aliphatic polyester. The procedure can be implemented as mass polymerization without the use of a solvent or other medium. The grafted starch derivative produced can be used as a component in hot-melt adhesives and as an impermeable coating for paper and cardboard.
