| Abstract: | The membrane softnesses of vinyl acetate (VAc)/Butyl acrylate (BuA) copolymers of various copolymer compositions were investigated by transmission electron microscopy (TEM) and differential scanning calorimetry (DSC) techniques. Glass transition temperatare ( T g) determined from DSC indicated the membrane softness was increased with increased BuA content. The relations between the membrane softness of VAc/BuA copolymer and the partical size measured by TEM, the amount of initiator, pH of meduim as well as the feeding method of raw material, respectively, were studied too. The good soft membrane was obtained by using the suitable proportion of monomers and excellently operating method. |
