The monomers were polymerized using ammonium persulphate as initiator. The polymers were then cross-linked with ethyleneglycol dimethacrylate as crosslinking agent. The prepared microparticles were characterized by FT-IR and DSC for drug and polymer compatibility and surface morphology of the particles was studied by SEM. FT-IR and DSC studies showed no chemical interaction between the drug and polymers. The release of drug followed Non Fickian diffusion type.
