Synthesis and Properties of Poly(BMA-co-PEGMA) Microspheres

Poly(butyl methacrylate-co-polyethyleneglycol methacrylate) (Poly(BMA-co-PEGMA)) microsphere was prepared by precipitation copolymerization of PEGMA and butyl methacrylate in ethanol solution. Microspheres were controlled by experimantal conditions 140nm to 210nm. The particle size of Poly(BMA-co-PEGMA) microspheres was decreased with increasing the concentration of PEGMA and increased with BMA of monomer.
