PCT No. PCT/FI95/00148 Sec. 371 Date Nov. 27, 1996 Sec. 102(e) Date Nov. 27, 1996 PCT Filed Mar. 21, 1995 PCT Pub. No. WO95/25750 PCT Pub. Date Sep. 28, 1995The invention relates to a procedure, to a grafted starch derivative produced by this procedure and method of using it. 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. |
