Synthesis in pilot plant scale and physical properties of sulfonated polystyrene

摘要: The homogenous sulfonation of polystyrene was developed in a pilot plant scale producing polymers with different degrees (18 to 22 mole % sulfonated styrene units). reaction yield depends chiefly on the concentration ratio acetyl sulfate and polystyrene. morphological thermal properties obtained by homogeneous were studied means scanning electron microscopy, differential calorimetry thermogravimetry. glass transition temperature increases relation pure DCp evaluated order confirm strong interactions among ~SO3H groups.
