ABSTRACT

The isolation and spectral data of seed extracts in various solvents of Pithecellobium dulce(PD) was done. The synthesis of acrylamide-grafted gum and efficiency was carried out by microwave-assisted free radical polymerization using silver nitrate and ascorbic acid. A table of graft copolymers was prepared, varying in the amount of acrylamide, AgNO3, thermal grafting & microwave irradiation time.FTIR and Chromatographic studies characterized these graft copolymers. Comparing grafting factors such as efficiency, percentage grafting and percentage conversion was carried out among various graft copolymers and then correlated with elemental analysis.
