Beschreibung
Zusammenfassung:The invention relates to a polyvinyl alcohol blend which comprises 30-98wt% of polyvinyl alcohol and 2-70wt% of poly(methyl) acrylate with a hydrophilic alcoholic hydroxyl group. The poly(methyl) acrylate with a hydrophilic alcoholic hydroxyl group is used as a plasticizer for plasticizing polyvinyl alcohol, and the obtained polyvinyl alcohol blend has higher physical properties such as faster water solubility and higher water absorption and softness. Therefore, the blends can be widely applied to the animal wound and particularly the wound or tissue of a human body. The softness of the film formed by the polyvinyl alcohol blend ensures that the material does not damage the wound.
