Extracted lignin from oil palm empty fruit bunch as natural eco-friendly poly (vinyl chloride) photo-stabilizer

In this work it was used extracted lignin from oil palm empty fruit bunch by kraft delignification process as environmentally friendly photo-stabilizer of Poly (vinyl chloride) thin films. Up to date writing this paper, nobody has used this type of extracted lignin as PVC photo-stabilizer. Therefor...
