Synthesis and Characterization of Acrylic Based Copolymeric Hydrogel Nanoparticles : An Approach to Drug Delivery

Poly(acrylamide-co-acrylic acid) copolymeric hydrogel nanoparticles(HN) were prepared by precipitation polymerization technique using potassium per sulphate(PS) as reaction initiator and N, N methylene-bis-acrylamide (MBA) as crosslinking agent.The prepared HN were characterized by FTIR and copolymerization was confirmed. From the swelling studies of the HN… CONTINUE READING
