Commerical Hibiscus sabdariffa is known for delicacy and also for medicinal properties .The
present paper deals to study the extraction in aqueous solution of leaves shows best results in which phenolics have been found to be present more in leaves , the extracting result was cured with different percentages of (8-hydroxyquinoline)(2%, 4% , 6%) , polymerization takesplace in presence of formaldehyde . The grinded resin was characterized by (IR),DSC and CHN analysis . The resin was used as a chelating polymer for the investigation of loading capacity (L.C) of [Bi+3 , Fe+3, Ni+2 ] from their diluted solution (100ppm) , The (L.C) of the resin was determined using (uv-v) spectrophotemetry as a function of both shaking time & pH . The metal ion solution optimum L.C. of the resin was found as following order .
Bi3+ > Fe3+ > Ni2+

During this research, some chemical modifications have been done on linear polymethacrylic acid.
Obviously, chemically modified polymers [6, 7, 8, 9, 10] have new different chemical and physical properties, with expected new industrial application. This research describes the synthesis of new modified polymers. Through the condensation of methacrylic polymer with appropriate acid hydrazide in the presence of phosphorus oxychloride. Where prepared many modified polymers in this method.
The structures of these new modified polymers have been established on the basis of physical and spectral data (FT-IR and UV). Acid number, viscosity, molecular weight and swelling of the polymers were also determined.
