Acetoacetyl-group-containing polyvinyl alcohol resin powder, and method for producing same |
| abstract |
Acetoacetyl group-containing polyvinyl alcohol resin powder containing a C1 to C3 alcohol in an amount of 0.5 to 4 wt% is produced by allowing a powdery polyvinyl alcohol resin to react with diketene, washing the resulting acetoacetyl group-containing polyvinyl alcohol resin particles with the C1 to C3 alcohol to remove an unreacted portion of the diketene, and drying the acetoacetyl group-containing polyvinyl alcohol resin particles at a temperature of 40°C to 120°C at a pressure of not higher than 20 kPa after the washing. The acetoacetyl group-containing polyvinyl alcohol resin powder thus produced is highly soluble in water. |
