| titleOfInvention | Polyvinyl alcohol resin powder composition and its manufacture method containing acetoacetyl |
| abstract | In the present invention; after making polyvinyl alcohol resin powder and diene reactive ketone; the polyvinyl alcohol resin powder containing acetoacetyl obtained by reaction is washed with the alcohol of carbon number 1~3; remove unreacted diketene; afterwards; the polyvinyl alcohol resin powder composition containing acetoacetyl as intermediate after 40~120 DEG C of temperature, below pressure 20kPa make above-mentioned washing is dried, and thus obtains the polyvinyl alcohol resin powder composition containing acetoacetyl of the weight % of alcohol 0.5~4 containing carbon number 1~3.The polyvinyl alcohol resin powder composition containing acetoacetyl so obtained possesses excellent water solubility. |
