Abstract:
Disclosed is a polyvinyl alcohol composition, a preparation method therefor and a use thereof. The raw material comprises the following components: 60-90 parts of polyvinyl alcohol and 0.1-3 parts of glutaraldehyde. The polyvinyl alcohol composition is prepared by mixing polyvinyl alcohol in a molten state with glutaraldehyde in an acidic environment. The invention has the following advantages and effects: the polyvinyl alcohol composition comprises polyvinyl alcohol, glutaraldehyde, acid, urea, etc.; when glutaraldehyde and polyvinyl alcohol undergo a crosslinking reaction, the decomposition temperature of the polyvinyl alcohol composition is increased, and the melting point of the polyethylene composition is decreased, so as to increase the workability of the polyvinyl alcohol composition. A polyvinyl alcohol medical use catheter prepared from the polyvinyl alcohol composition has excellent biocompatibility and is convenient for doctors to use clinically. The polyvinyl alcohol composition can also be used for preparing various kinds of articles, such as a sealing gasket, a degradable flower pot, a tote bag, etc. The polyvinyl alcohol composition has a low melting temperature, is easily applied to melt processing, demonstrates excellent biocompatibility, and has a wide range of applications.
