Abstract:

The etherification of nata de coco was achieved through an SN 2 reaction of the freeze dried sheet of the biopolymer with alkyl bromides. Two ether derivatives of nata de coco were separately prepared using 1- bromohexane and 1,6-dibromohexane in warm (50-60o C) pyridine. The resulting products were tested for its swellablity and compared with that of the unreacted nata de coco. Characterization was done using SEM and ATR FT-IR.
