Abstract
Poly(vinyl acetate–methyl methacrylate) (VAc–MMA) copolymer microspheres were prepared using suspension polymerization at low temperature initiated with 2,2′-azobis(2,4-dimethyl valeronitrile) (ADMVN). The poly(VAc–MMA) copolymer microspheres can be used over a large area where homopolymers, polyvinyl acetate (PVAc) and methyl methacrylate (PMMA) microspheres are capable of being put to use. The prepared microspheres were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), differential scanning calorimetry (DSC) and thermal gravimetric analysis (TGA). Obtained copolymer microspheres which have 200μm average diameter and higher thermal stability than those of homopolymer.
