| titleOfInvention |
Polyvinyl alcohol powder |
| abstract |
The present invention provides a polyvinyl alcohol powder which comprises a pore having an average diameter of 0.1 to 10 µm in the range of 0.05 to 0.4 cc/g. Since the PVA powder of the present invention has an excellent solubility in water, an aqueous solution thereof can easily be prepared industrially. Since the PVA powder of the present invention has a low content of an organic volatile component and a low content of a nonvolatile component such as a carboxylic acid salt or the like which is derived from a basic catalyst, it has an excellent industrial handleability. |
