Introduction: Modified polymeric materials are nowadays most commonly used for making modified release pharmaceutical dosage forms. Methods: In this present research study, a grafted copolymer is synthesized by using acrylamide and okra gum with the help of the redox initiator method. The method was optimized using a 3-factor, 2-level central composite design (CCD). Optimization of the synthetic process was done by the application of QbD, amount of acrylamide (1-10g), amount of initiator (50-150 mg), and microwave irradiation exposure time (1-5 min) were taken critical process variables and response factors were selected as percentage grafting (% grafting) and percentage yield (% yield). Results and Conclusion: The optimized formulation (F13) having a maximum percentage of grafting 82.2 and a percentage yield of 12.54 of the formulation’s acrylamide (5.5g), amount of initiator (100 mg), and microwave irradiation exposure time (3 min). Characterization of synthesized grafted copolymer product was performed by using differential scanning calorimetry (DSC), FT-IR spectroscopy, and scanning electron microscopy (SEM). |
