Polyvinyl alcohol powder |
| abstract |
The present invention provides a polyvinyl alcohol powder comprising pores having an average diameter of 0.1 to 10 μm in the range of 0.05 to 0.4 cc / g.n n n Since the PVA powder of the present invention has excellent solubility in water, its aqueous solution can be easily produced industrially.n n n The PVA powder of the present invention has excellent industrial handleability because of the low content of organic volatile components and the low content of non-volatile components such as carboxylic acid salts derived from basic catalysts. |
