HOMO-POLYACRYLONITRILE REMOVAL AFTER CHEMICAL GRAFTING PROCESS: BY TEA BAG EXTRACTION METHOD

Abstract

In this study, the homopolymer from the grafting solution between two monomers; acrylonitrile and microcrystalline cellulose was purified using tea-bag method technique. Microcrystalline cellulose (MCC) was used as monomer backbone and the acrylonitrile will graft onto its surface. The result of tea-bag method extraction shows that the homopolymer can be isolate from the mixture of the solution. The residue of homopolymer was visualized using scanning electron microscope. The residue was trapped on the tea bag surface. Also, the physical appearance of the polymer before and after grafting also discussed in this study. The tea bag technique can be used as the extraction method in removing homopolymer after grafting polymer process.
